Tom Arnold Announces His Wife Is Expecting a Daughter

— -- Tom Arnold and his wife are expecting a baby.

The comedian made the announcement by sharing a photo of his 2-year-old son Jax holding a sonogram.

"Jax is very excited but also a bit confused with the happy news he will have a little sister this fall. #grateful," he tweeted.

Arnold, 56, married his wife Ashley in 2009. They welcomed their son in 2013, which was the impetus for his 100-pound weight loss.

"Something inside of me changed," he told People last year. "I knew I needed to live as long as I could. ... The moment I saw [Jax], I realized he deserves the best."
