Michelle Monaghan has signed on to star opposite Patrick Dempsey in the romantic comedy, Made of Honor for Columbia Pictures.

Paul Weiland will direct from a screenplay from Deborah Kaplan and Harry Elfont; the story chronicles the relationship between Tom (Dempsey) and Claire (Monaghan), who have been platonic friends for 10 years. The Hollywood Reporter adds he's a serial dater, while she wants marriage but hasn't found Mr. Right. Just as Tom is starting to think that he's relationship material after all, Claire gets engaged. When she asks Tom to be her "maid" of honor, he reluctantly agrees - only so he can attempt to stop the wedding and woo her before it's too late.

Shooting on Made of Honor is scheduled to start in April.
