Conan O'Brien Ends Late-Night Run; Chris Pratt, Mindy Kaling, Seth Green Pay Tribute To Host

Conan O'Brien is finally saying goodbye to late-night television after 28 years. He ended his TBS show "Conan" on Thursday.

O'Brien concluded his show by thanking everyone who helped him, including its writers, executives, agents and managers. He also thanked Lisa Kudrow for giving him enough confidence to replace David Letterman as a late-night television host in 1993.

Many celebs took their social media handles to pay a tribute to the talk show legend.

Chris Pratt took to Instagram on Thursday evening to share a throwback photo of him during an interview with O'Brien.

"This is me on Conan 11 years ago," he wrote. "My first talk show. I think I stood up in the middle of the interview to take my jacket off at one point. He's been a friend and supporter since day one. Much love #teamcoco."

Actress Mindy Kaling also paid tribute to the host by sharing a fun fact. "I used a @teamcoco quote in my high school yearbook," she wrote. "He was 'that' important to me as young person interested in comedy."

Kaling recalled that she worked as an intern on his show when she was 19. "He took the time to be nice and encouraging to me, even though I was weird and ineffective," she said.

Actress Jameela Jamil posted a message on her Instagram Stories. She wrote, "I will miss his late-night interviews so much. I'm so lucky I had the honor of getting to be his guest."

She also shared one of her interviews with the 58-year-year old host and captioned it, "Lean into imposter syndrome! This was the most fun interview of my life."

"Conan is so quick and funny and warm and engaging here. I am in awe of his gift as an interviewer and I have loved him my whole life almost," she added.

Standup comedian Bill Burr also shared a throwback photo and wrote, "I had so much fun over the years on @teamcoco show. It’s the end of a major era in late-night history. You were the best!"

Actor Seth Green shared some fun moments he had when he appeared on the show.

O'Brien began his late-night television career on NBC with "The Tonight Show." He will be next seen on an HBO Max show. But no details have been revealed about it yet.
