Courtside cutie! Justin Bartha made it a family affair when he and his wife, Lia Smith, attended the US Open Tennis Championships in Queens, NYC on Sunday, Sept. 6. The couple kept entertained by watching the matches and their seat buddy — daughter Asa Charlotte!

Watching the Marin Cilic vs. Jeremy Chardy match inside the Arthur Ashe Stadium, the Hangover actor, 37, and Smith coordinated in matching black sunglasses for the rare public appearance. Asa, 16 months, looked adorable in a white dress and appeared to have her famous daddy's blue eyes.

Us Weekly confirmed in January 2013 that Bartha and the fitness trainer were dating. They tied the knot exactly one year later in Hawaii, with stars like Reese Witherspoon and Jesse Eisenberg in attendance. Already pregnant at the nuptials, Smith gave birth to their first child that April.

"[Lia] had her hand on her stomach most of the time," an insider told Us at the time. "[It] looked like she had a little bump."

Bartha previously dated Ashley Olsen from 2009 to 2011.
