Moynahan married New York businessman Andrew Frankel in a beautiful ceremony in the Hamptons.

Moynahan shared some lovely photos from her big day on Instagram.

“Oh, by the way, guess what I just did #sohappy #perfection #friends #family #forever,” the actress captioned this photo:

Moynahan’s wedding was a bit of a surprise – as is wasn’t highly publicized beforehand. Moynahan and Frankel’s relationship is pretty low-profile, at least compared to the one she had about a decade ago. Moynahan was with New England Patriots quarterback Tom Brady until 2006. They have a son together.
