A source confirmed the birth to Us Weekly but details on the gender, name and weight were not available.
Miller is perhaps best known for her on-off relationship with Law, who famously cheated on her with his kids’ nanny. The pair split in 2011 after a friend says the relationship “had run its course.”
And that very public humiliation made her understandably gun-shy about having living her life in the spotlight.
So don’t expect to see her tweeting every detail about her life as a mom. “I’m under strict instructions not to say anything as it would completely defeat the point of everything I’ve tried to achieve in the last eight years,” she recently told British Vogue.
Congrats to the new parents!
