Chad Lowe Welcomes A Girl!

It's a girl for Chad Lowe and his girlfriend, producer Kim Painter, the actor's rep confirms.

Daughter Mabel Painter Lowe made her debut on Saturday in Los Angeles. "Everybody is healthy and happy," says the rep.

The couple announced the pregnancy in January, with Lowe explaining that Painter revealed the baby news to him with a grin. "She woke up with a very big smile on her face and I knew exactly what that meant," the Emmy-winning actor, 41, told Access Hollywood.

Lowe and Kim began dating in January 2007. Mabel is the first child for the couple.
