Matthew Perry often finds himself getting confused between his own personality and that of his 'Friends' character Chandler Bing.
The 42-year-old actor - who played the funnyman for 10 years until 2004 - admits the character's traits does slip into his every day interactions and he sometimes has to decide what his authentic self is.
Asked if Chandler is still part of his life, he said: ''Yes, he does, but a lot of that is me too, so you have to try to figure out which is which.''
Matthew is now working on comedy drama series 'Go On', in which he plays sportscaster Ryan King and he admits he loves working with his new co-stars, who include John Cho, Julie White and Laura Benati.
He told Access Hollywood: ''It's a really good group of people. Everywhere you look there's smart, funny people. We're just at the stage now where the writers start to work towards people's personalities. But this guy is going through some more heavy stuff. That's the other thing to keep in mind.''
Matthew's former 'Friends' co-star Matt LeBlanc has recently claimed he can foresee no plans for the cast - who also includes Jennifer Aniston, Lisa Kudrow, Courteney Cox and David Schwimmer - ever working together again.
He said: ''I think it's a bit of a case of 'the book is better than the movie'.
''Everyone identifies with those characters in their own way and everyone in their own mind imagines what has become of those characters. I just think it's best to leave it at that.''
