Tom Arnold's family just gained a new member!
The 56-year-old Hit and Run star and his wife, Ashley Groussman, welcomed their second child together, a girl, on Friday, the actor's rep confirms to ET. Quinn Sophie Arnold was born in Los Angeles at 12:39 p.m., weighing in at 7 lbs, 9 oz., and measuring 22 inches long.
Tom announced he and Ashley were expecting baby No. 2 in June, with an adorable photo of Jax, their 2-year-old son.
"Jax is very excited but also a bit confused with the happy news he will have a little sister this fall," he tweeted, with the hashtag "#grateful."
Looks like the comedic actor will have to add the new bundle of joy's name to his Twitter bio, which currently reads, "Iowa Hawkeye. Former Meat Packer. Current Old Dad. Co-Creator of Jax."
Prior to the newborn's arrival, Jax has been the only toddler making consistent appearances on his dad's Instagram. We think it's safe to say, however, that it's only a matter of time before his little sister becomes an Iowa Hawkeyes fan!
"Iowa Hawkeye pride has taken over Beverly Hills California!" Tom captioned a pic of the father-son duo cheering on his alma mater's football team earlier this month.
Proving he's the coolest father of them all, he shared a snap of Jax trick-or-treating at an A-lister's house in October.
"Happy Halloween! How many other cool dads took their sons to Charlie Sheen's house??? #GoHawks #BeSafe," he wrote.
We're already looking forward to all the 'first' photos Tom will share as the newborn grows up, like this one, of Jax's first school pic.
