Carol Burnett just turned 90!

The comedian and star of The Carol Burnett Show celebrated her 90th birthday last evening, April 26, with a slew of celebrities who paid tribute to her during the NBC special Carol Burnett: 90 Years of Laughter + Love.

Many famous friends of Burnett took the stage at Avalon Hollywood in Los Angeles, Calif. to honor Burnett with musical performances and skits, including Katy Perry who sang, “I’m So Glad We Had This Time Together” by the legend herself.

Perry and Burnett even shared a sweet moment together, when the 38-year-old singer approached the comedian who sat in the audience, giving her a chance to sing to the lyrics: "Comes a time we have to say 'so long.'"

"Oh God, thank you, everybody. Oh wow," Burnett said as she did her signature ear tug.

Sheryl Lee Ralph also attended the ceremony and took to Twitter to share a few photos from the wonderful evening.

The Abbot Elementary star, 66, snapped selfies with the birthday girl herself, along with three other snaps with Kristen Chenoweth, Bernadette Peters, and Steve Carell, who all attended the event.

"Happy Birthday to the amazing Carol Burnett and thank you for the honor of sharing it with you," Ralph wrote.

Other celebrities took to their Twitter accounts to wish the comedian a happy birthday, including 96-year-old Tony Bennett who wrote, "Wishing the lovely, talented and wonderful #CarolBurnett a very happy 90th birthday today. Susan and I are all set to tune in to the tribute special airing on #NBC tonight to celebrate her incredible career."

Deana Martin, daughter of Dean Martin also shared her birthday wishes.

"Happy 90th Birthday to our dear friend Carol Burnett ... the funniest and most creative lady in show business," she wrote alongside photos of Burnett, Elizabeth Montgomery, and her father.

Actor Maureen McCormick, most famously known for her role as Marcia on The Brady Bunch, also tweeted birthday wishes to the comedian, writing, "I will never be able to thank you enough for all the joy you brought into the house I grew up in."

She continued: "That joy is deeply embedded in me and my love and respect for you have only grown with time. Thank you for gracing us with your brilliant talent! Happy Birthday Carol Burnett."

Happy birthday, Miss Burnett!
