Paul Rudd has signed on and Jason Segel is in negotiations to star in DreamWorks' comedy I Love You, Man, according to Variety. Both actors appeared in this year's summer comedy Knocked Up.

John Hamburg (Along Came Polly), who signed a two-year overall deal with DreamWorks in April, will direct.

Hamburg wrote the script which centers on a man about to get married who actively seeks out a male friend to be his best man for the wedding.

Shooting is scheduled to start in March.
