Conan O'Brien Shares The 1 Thing That Made Him 'Jealous' Of Matthew Perry

Conan OBrien still remembers how jealous he was of late Friends star Matthew Perry .

The comedian admitted as much on Mondays episode of the Conan OBrien Needs a Friend podcast and reminded guest Lisa Kudrow who landed her part on Friends shortly after breaking up with OBrien that she couldnt stop talking about her co-star.

You started doing that show, and you called me up and you were raving about Matthew, and you were saying, Hes so funny, and there was part of me that was jealous, OBrien said. I was [like], OK, I make you laugh pretty hard.

And you were like, No, you dont understand this guys really [funny], he continued.

OBrien and Kudrow started dating in 1988, when both were relatively unknown Hollywood talents . The couple ultimately broke up one year before Friends premiered in 1994, and despite his initial reaction, OBrien had to agree with Kudrows assessment of Perry, who played the sarcastic Chandler Bing.

I was watching him and going, Yep, OBrien said.

Kudrow, who played lovable ditz Phoebe Buffay on the show, assuaged her ex-boyfriend by calling OBrien one of the funniest people I know.

Thats just a fact, she said. But [Perry] was such a huge [star].

Perry was found dead in October last year at 54 years old in what looked like an accidental drowning. An autopsy released in December found Perry had high levels of ketamine in his system at the time; the report listed the drugs acute effects as his primary cause of death.

On OBriens podcast, Kudrow shared that she started binge-watching Friends after Perrys death.

Well, I used to not be able to watch it at all ... after Matthew died, I could start watching the show again because it wasnt about me. It had to do with him, she said, adding, I have spent, at times since he died, all day long watching the show.
