The 100-year anniversary of the Grand Ole Opry is being celebrated on Wednesday night.
Country superstar Blake Shelton is hosting the event, titled the "Opry 100: A Live Celebration," on March 19, which is airing on NBC. The official 100th anniversary of the Grand Ole Opry is in November, and the country music house will be celebrating all year long.
Jelly Roll, Reba McEntire, Post Malone, Carrie Underwood, Trace Adkins, Lainey Wilson and Kelsea Ballerini are all set to take the stage.

"To get to be here tonight to celebrate the 100th anniversary, I wouldn't miss this for the world."

On the carpet, Pearce made comments during the official Grand Ole Opry pre-show livestream about her debut in country music and how proud her grandparents would be to see where she is now.
Pearce said during her debut, she saved two seats in the audience for her grandparents, who passed away prior to her big moment. Now, she knows they would be overjoyed to see her honoring Dolly Parton during the century's celebration of the Grand Ole Opry.
Yearwood also stuck to a black theme and wore a black sequined gown.
