Patrick Dempsey dons a tuxedo on the Hollywood set of his upcoming romantic comedy Made of Honor Monday morning

Co-stars Michelle Monaghan and Kelly Carlson were also on set to film scenes of a wedding reception.

It was reported earlier this week that Sydney Pollack, Kadeem Hardison and Beau Garrett joined the cast.

Made of Honor revolves around Tom (Dempsey) and Claire (Monaghan), who have been platonic friends for 10 years. He’s a serial dater, while she wants marriage but hasn’t found Mr. Right. Pollack will play the father of Tom.

Just as Tom is starting to think that he is relationship material after all, Claire gets engaged. When she asks Tom to be her “maid” of honor, he reluctantly agrees just so he can attempt to stop the wedding and woo her.

Kelly Carlson gets tucked in by a new man as she ‘walks down the aisle’ on the set of Made of Honor in Los Angeles on Friday.

Grey’s Anatomy star Patrick Dempsey is supposed to be playing a man in love with his best friend (Michelle Monaghan) but forced to be her “maid” (man?) of honor.

How Carlson’s character is woven into that storyline is still unknown.

Carlson, 31, is best known for her role as adult-star-turned- Scientologist Kimber Henry on Nip/Tuck.
