They may be some of the most famous faces in the world, but some celebrities look so similar they could pass for being related – you just might not have realised it yet.
From Kate Middleton to Keira Knightley to Margot Robbie and Jaime Pressly, there are some pretty wild dopplegangers out there.
While it may not seem ideal to have a fellow famous doppelgänger, some have been able to benefit from it.
Some have been cast in films as siblings or have confessed to using someone else's name to gain access to exclusive events before they came famous.
Here, MailOnline reveals 28 of the most famous faces in the world and which fellow celeb could pass as their twin.

Kate Middleton and Lauren Conrad
The Princess of Wales, Kate Middleton, is adored by millions across the globe and has one of the most famous faces in Britain.
But despite her iconic look, many often mistake American TV personality and fashion designer, Lauren Conrad, 38, for the beautiful royal.
Lauren, who is known for her role on Laguna Beach: The Real Orange County, has similar high cheekbones and smile to Kate, 42.
The pair have both sported light brown curly hair in the past and both typically opt for natural-looking makeup.
But it is not even just their looks that are similar, as they are also both married to men called William.
Kate married Prince William in April, 2011, and Lauren tied the knot with her partner William Tell in September, 2014.
And while comparisons of the two beauties have been swirling for years, Lauren previously told Fashionista that she doesn't see any similarity between them.
She said: 'I don't actually see it!'
'I mean, listen, it's like the ultimate compliment, A lot of women want to look like her so I'll take it,' she added.

Keira Knightley and Natalie Portman
With dark hair, doe-like eyes and lithe frames, many struggle to tell the difference between British actress Keira Knightley and Israeli-American Natalie Portman.
But from the beginning of her stardom, Keira knew of the uncanny resemblance because at the age of 12, Keira, now 39, was hired as an actress due to her close resemblance to Natalie.
At the time, Natalie had secured the role of Queen Padme Amidala in Star Wars: Episode I – The Phantom Menace.
And with Keira having an undeniable similarity, she played the part of Queen Amidala's handmaiden Sabé.
These starring roles were the start of their doppelgänger connection as many people had trouble telling them apart when they were in full costume.
During an episode of The Late Late Show With James Corden, Keira revealed that she was once chased through an airport by a fan who thought she was Natalie.

Timothée Chalamet and Natalia Dyer
Even some of Hollywood's biggest stars have a fellow famous acting double of the opposite gender.
Dune star Timothée Chalamet, 28, and Stranger Things actress Natalia Dyer, 29, look so similar that some fans were convinced they were related.
The two acting stars have a very similar chin and this paired with their curly brown locks is said to make them look twin-like.
Their similar looks sent their fans into a frenzy when they first made the comparison in 2019 and fans since have begged for a film to star them as siblings.

Margot Robbie and Jaime Pressly
The resemblance between Margot Robbie and Jaime Pressly has been a talking point for films buffs for over a decade.
Margot Robbie was 2024's classic Barbie beauty and the pair's blonde locks, blue eyes and strong jaw lines have led to years of confusion.
And despite the pair having completely different accents and body builds, fans can't help but get the two mixed up.
Even in 2018, fans were left scratching their heads during dark dramedy I, Tonya, as some viewers were left confusing Margot, 33, with Jaime, 46, through the film.
Jaime has previously addressed her striking similarity with Margot in 2016, joking that the Once Upon A Time… in Hollywood looked like her – not the other way around.
When photographers asked whether she'd noticed the likeness, she was quick to respond.
'Right, well that would be she looks like me!' she quipped.
The Not Another Teen Movie star added that she was a fan of Margot's work.
'I think she's great yeah, I've loved everything she's done.'

Jeremy Allen White and Gene Wilder
Some stars are so similar in facial features and hairstyles that fans have questioned possible distant relations.
The Bear star Jeremy Allen White was first compared with Gene Wilder in 2022 following the release of his famous Netflix TV show.
And while Jeremy may have similar mousy curly looks, piercing blue eyes and diamond cut jawlines, the actor has vehemently denied any relation.
Previously speaking to Buzzfeed, Jeremy said: 'I'm not related to Gene Wilder,'
'I think a lot of people think I am,' he added.
The pairs' uncanny resemblance was of a talking point again last year after the trailer for the new Wonka film, starring Timothée Chalamet in the titular role, was released.

Millie Bobby Brown and Elizabeth Perkins
Similar to Kate and Lauren, Millie Bobby Brown and Elizabeth Perkins's classic looks mean they also often get mistaken for one another.
After Millie, 20, made her breakthrough as Eleven in the Netflix series Stranger Things in 2016, fans became crazed with her likeness to The Flintstones star, 63.
With their long brunette tresses, circular framed face and bow heart lips, it is no surprise that people thought they were seeing Elizabeth as a younger self.
The pair's similar features first became glaringly obvious after a comparison TikTok clip was created by user @shuhuhuh.
The video featured a slideshow of images of the two actresses side by side, generally in similar settings or poses.
Though Elizabeth is older than Millie, the Big actress might give the young actress a glimpse into what is to come.

Jenna Ortega and Taylor Russell
Their chocolate brown doe-eyes, button noses and no-nonsense glares have previously sent their fans into a frenzy over who's who.
Wednesday star Jenna Ortega, 21, and Taylor Russell, 29, have been rumoured to be sisters for over a year.
But despite Jenna having five siblings, Bones And All actress, Taylor, is not one of them.
The acting sensations are not related in any way. They just hold themselves in a similar poised aura and have similar stunning features.

Katy Perry and Zooey Deschanel
Dark hair, pale skin and huge blue eyes – it's no surprise Katy Perry and Zooey Deschanel often get mistaken for one another.
But their similarities are nothing new to Katy, 39, and she said that before she found fame, she use to pretend to be Zooey, 44, to get into nightclubs.
Katy was speaking on an Instagram Live, alongside Zooey, ahead of the release of her 2020 music video Not The End of the World, where aliens mistake the New Girl star for the singer and abduct her.
Speaking at the time she explained: 'When I moved to LA, maybe 18 years ago, I was pretty much a nobody, and you were like just getting so huge at that time, it was like Zooey Deschanel ran the world. In that moment, I was so complimented to look like you.
'I have to admit something to you.
'When I first got to LA, I went to the club. A lot. And I wanted to get into the club, but I had no money, I had no clout, I had nothing, and sometimes I would pose as you to get into the club'.

Famous redheads Isla Fisher and Amy Adams are often mistaken for one another and have often posed together to dispel myths they're the same person.
Speaking to the Project in 2020, Isla said fans mistaking his identity hadn't happened 'for a while' due to lockdown – but in regular times it happened all the time.
'I haven't had it for a while, but I think I've been inside my house in COVID for a year,' she joked.
'We laugh about it because Amy has blue eyes and I've got brown, our husbands have laughed about it, too,' she added.
They look so a-like that even celebrities have confused the two, as Isla previously revealed that Lady Gaga mixed the pair up.
Speaking to Jimmy Kimmel about the 2017 Vanity Fair Oscar party, she explained: 'I was there all fancy and dressed up at the bar and schmoozing with showbiz types, and the crowds parted and there was Lady Gaga,'
'She's heading right towards me and she says, 'Thank you. Your performance in American Hustle, Amy, was…''
Deciding not to correct her, she explained: 'I love her so much, I [didn't] want to tell her the truth. So I just gracefully thanked her [and] bowed my head.'
But Gaga wanted to discuss the performance, and Isla knew she was in trouble.
'I [looked] over [Gaga's] shoulder and there's Amy Adams walking into the party,' Isla told Kimmel.
'So I said, 'There's Isla Fisher. She's not even nominated for anything, what's she doing here?'

The Jurassic World star, 43, detailed how she had been confused for Jessica, 47, long before their acting careers even took off and conceded that the pair 'could be sisters'.
She explained: 'It's very flattering for me! It's odd because it all started long before we were famous.

Despite the long-running joke, the Black Mirror actress said their first run-ins with confused fans was a 'little unnerving' but did admit that she can see where people are coming from, adding 'we could be sisters'.
