Preparing for her upcoming gig as a co-host on "Ellen," Jennifer Aniston reached out to her pals Courteney Cox and Matthew Perry for advice on Tuesday (May 21).

In a hilarious clip, the former "Friends" cast mates confuse each other with other cast members when Jen arrives at Perry's house, thinking he is David Schwimmer and Cox confusing Jen with Lisa Kudrow.

Co-hosting the popular day time talk show will be the "Just Go with It" cutie's first foray in to hosting duties.

Fans can tune in to "Ellen" on Wednesday on their local ABC station. Check out the clip starring the confused co-stars in the player below!
