Anna Faris and Chris Evans are set for New Regency's R-rated comedy What's Your Number?, directed by Mark Mylod.

According to Variety, What's Your Number? revolves around a young woman who, with the aid of her womanizing next door neighbor, decides to re-visit all her ex-boyfriends in the hopes of finding the man of her dreams.

What's Your Number? is based on Karyn Bosnak's tome "20 Times a Lady." Bosnak originally adapted the book for the bigscreen; her script was rewritten by Jennifer Crittenden and Gabrielle Allan.

Before landing at Regency, the project was at New Line, then Sony.

The project will begin production in May.
