42-year-old actor confirms that Wilson and girlfriend Jade Duell welcomed a baby boy in Hawaii on Friday. The actor kept news of Duell's baby bump a secret until Monday -- but a source recently told Us that Wilson was "very exited and involved with the pregnancy."
The first-time dad -- whose past loves include Kate Hudson and Sheryl Crow -- "has been doing research and learning as much as he can," a source adds. "He's super into it and asks a lot of questions to make sure he knows what's going on every step of the way."
