Arnold also hit Twitter to joke about becoming a first-time father later in life.

"Game Changer: Jax Copeland Arnold. 8lbs 12oz. Looking forward to being a 70 year old Little League Coach," he tweeted.

Arnold -- who was married three times, including to Roseanne Barr, before tying the knot with Groussman in November 2009 -- has been candid about his struggles with infertility.

“I’ve tried with other people, but since there is a God we were unable to conceive. Now God said, ‘This is it!’” Arnold told People in January.

Arnold, the former co-host of Fox Sports Net's The Best Damn Sports Show Period, is best known for roles in films like True Lies. He recently appeared in the film Hit & Run and guest-starred on CBS' Hawaii Five-0.
