Bridget Moynahan Was 'Heartbroken' and Pregnant After Brady Break-Up

Bridget Moynahan says she had a "traumatic time of being heartbroken" and pregnant after the relationship with her baby's father, New England Patriots quarterback Tom Brady, ended.

"I'm not sure anyone — and I could be wrong in this — grows up thinking, 'I want to be a single mom,'" Moynahan, 37, says in the July issue of Harper's Bazaar, according to

Shortly after the end of her three-year relationship with Brady — who is dating supermodel Gisele Bündchen — Moynahan announced her pregnancy.

"When you're suddenly pregnant and no one is standing by your side, even if you're in your 30s, it's a hard conversation. I'm a traditional girl, and I believe in marriage, and I just always thought that's the way I'd be doing this," she says. "For a moment, it was hard for me to accept that this was the way I was going to have a family."

She gave birth to John — whom she gave her last name — last August.

"I walk in and just started sobbing," she says of coming home alone with her son. "All of a sudden, you have this newborn you have no training for. It's frightening."

But in the end, it was all worth it, she says.

"It's golden and it's tough and it was f—-ed up. But now I have a child, and it's the best thing in the world."
