In his new movie 'Made of Honor,' in theaters everywhere Friday, PATRICK DEMPSEY plays a sexy single guy looking to settle down -- and woo bridal buddy MICHELLE MONAGHAN in the process.

At Monday night's New York premiere of the romantic comedy, ET's own ordained MARY HART married a pair of lucky contest winners (SHAUN BOLLINGER and MICHELLE GOLIGHTLY) on the "pink carpet" in an emotional, romantic ceremony! The groom even donned a cashmere tux from celeb designer ARNOLD BRANT, while the bride looked beautiful in SELIA YANG.

Both Patrick and Michelle were there for all of the excitement, and the blushing bride could barely contain herself upon meeting the "Grey's Anatomy" heartthrob, saying, "He's hot!"

"I'm sure the couple's going to remember this for the rest of their lives," Patrick tells Mary.

In 'Made of Honor,' Patrick plays a serial dater who decides to settle down just as his best platonic friend (Monaghan) decides to tie the knot. Not content to let her slip away, Patrick accepts her invitation to be her "maid" of honor in order to win her heart.
