"Tommy, like everything else in our life, I share this [award] with you," she said. "And Matilda, it's one thing to be completely honest as an actor — it's another thing to be completely honest as a human being." "And that's just who you are and how you live, and you teach me just by being you," Williams added. Although the private couple mostly keeps out of the spotlight, they did walk the Golden Globe Awards red carpet together in January, with Williams keeping her baby bump under wraps.

"I always say to Matilda, 'Your dad loved me before anybody thought I was talented, or pretty, or had nice clothes.' " Us Weekly was the first to report the birth.
