"Project X" star Thomas Mann will join Kristen Wiig in the indie comedy "Welcome to Me," which is being produced by Will Ferrell and Adam McKay as well as Bron Studios, an individual familiar with the project has told TheWrap.

Wiig stars as a woman suffering from a personality disorder who wins the lottery and decides to finance a cable access talk show in which she discusses her life.

Mann will play an art student who is a big fan of Wiig's show and has a steamy encounter with her. He'll film his scenes later this month in Los Angeles.

Ferrell and McKay are producing through their Gary Sanchez Productions banner along with Jessica Elbaum, while Aaron L. Gilbert and Marina Grasic are producing for Bron. Margot Hand will co-produce and Robyn Wholey will executive produce.

Ever since he co-starred in Ryan Fleck and Anna Boden's comedy "It's Kind of a Funny Story," studios have been lining up to work with Mann. He played the lead in WB's Todd Phillips-produced comedy "Project X" and starred opposite Victoria Justice in Josh Schwartz's Paramount comedy "Fun Size." Mann clearly made an impression on those studios, as he quickly landed key supporting roles in WB's "Beautiful Creatures" and Paramount's "Hansel & Gretel: Witch Hunters."
