This is the first marriage for the Blue Bloods star, though she was previously in a three-year relationship with screenwriter Scott Rosenberg and has an eight-year-old son, Jack, with her ex-boyfriend Tom Brady.

Bridget and Tom — who now has two kids, Benjamin, 5, and Vivian, 2, with wife Gisele Bündchen — dated from 2004 to 2006 before calling it quits when the actress was about three months pregnant. Andrew is similarly a dad to three young sons from a prior relationship.
