Looks like the littlest Padalecki is the family's biggest sports fan!

On July 27, Supernatural star Jared Padelecki, 30, shared the first photo of his son, Thomas Colton, born March 19. "Thomas has some Olympic pride," the actor wrote in a Twitter caption. "Go USA!"

This is the first child for Padelecki and his wife, Genevieve Cortese, who wed in Sun Valley, Idaho on February 27, 2010. The pair waited until their son's birth before deciding on a moniker.

"We don't want to put it out there, like try and turn him into something before we meet the kid," Padelecki told Us Weekly prior to Thomas Colton's birth. "We want to get a feel for who this kid is before we name him."

Padalecki -- who's also appeared in New York Minute with Mary-Kate and Ashley Olsen and House of Wax with Paris Hilton and Chad Michael Murray -- recently finished taping the first episode of Supernatural's eighth season.

"Episode 1 done! Even though it's really episode 3," he tweeted July 18. "Well, actually it's episode 150!! Thanks y'all."
