For Bridget Moynahan, bringing her newborn son home alone last year was "frightening" – and far from a dream – she reveals to Harper's Bazaar
"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 magazine's July issue.
Shortly after the end
of her three-year relationship with New England Patriots quarterback Tom Brady – who is currently dating Gisele Bündchen
– Moynahan announced
"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 having family and friends like I, Robot
costar Will Smith
rally around her, made it easier. "I got so much out of that," she says of that "traumatic time of being heartbroken" and pregnant. "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."
