Bridget Moynahan, best known for her role as Erin Reagan on the hit CBS cop drama Blue Bloods, tied the knot in the Hamptons this weekend with businessman Andrew Frankel. It was Saturday evening amidst a small group of close friends and family members that the two said, “I do.”

Among those family members was Bridget Moynahan’s son Jack. Jacks is also the son of New England Patriots quarterback Tom Brady. Brady and Bridget Moynahan never married.

So who is this handsome groom who won Bridget Moynahan’s heart?

“The groom is from New York and is Co-President of Stuart Frankel and Co., a Wall Street institutional brokerage firm,” a source tells People magazine. “They met each other through a friend and she has been on cloud nine ever since.”

Moynahan shared word of her new status via Instagram.

“Oh, by the way, guess what I just did @johndolanphotog #sohappy #perfection #friends #family #forever,” she captioned a beautiful photo herself with her handsome groom.
