Cuoco shared a photo of the couple, dated Aug. 10, in which they can be seen sweetly nuzzling their faces. Cuoco proudly held up her hand to show off the square-cut engagement ring. "Amazing weekend," she wrote.

"What a wild, beautiful journey life can be," Cuoco added alongside a video close-up of the ring. "Grateful for every road that led me straight to you (Tom Pelphrey)."

The "Flight Attendant" star and Karl Cook broke up after three years of marriage in 2021.

Kaley Cuoco opened up about parenting to USA TODAY's The Essentials

Cuoco previously opened up to USA TODAY's The Essentials previously about parenting advice, but said she doesn't have a lot to offer on the subject.

"My advice is don't take any advice because every kid is different," she said. "What my kid needs is not what your kid needs, and our household is different than yours, and it's survival. You do what you can do.

"If she's going crazy, and I plop her on the couch to watch a Disney movie, like thank you, you get 10 minutes. That's great. To me, that's wonderful," she added.

"There's maybe the next mom who doesn't want them to watch TV, and that's fine too. But that definitely works for us."
