They grow up so fast! Twelve years after he played her son in 2002's Maid in Manhattan, Teen Wolf star Tyler Posey reunited with his former movie mom Jennifer Lopez at the 2014 Teen Choice Awards on Sunday, Aug. 10.

Posey, now 22 years old, introduced Lopez as a presenter at the event, which he co-hosted with Modern Family's Sarah Hyland. As she walked up to the mic accompanied by her new song, "Booty," he joined her onstage and gave her a little hug. "Hi, Tyler!" the American Idol host cooed at her onetime costar.

"I know we haven't seen each other since Maid in Manhattan, which was forever ago," Posey said of the rom-com, which starred J.Lo as a hotel maid/single mom who falls in love with a wealthy politician (Ralph Fiennes). "But I thought that maybe if you needed a backup dancer, I'd fit. What do you think?"

He then proceeded to show off some of his hottest booty-shaking moves for the "First Love" singer, 45. "If I say yes," she said, laughing, "will you stop?" As he walked away, she marveled, "It's crazy...he's so big! Oh my god." 

Lopez, for her part, hasn't aged a day since she and Posey shared the screen. She turned heads at the Teen Choice Awards in a green lace minidress with sheer sleeves and a flared skirt that showed off her sexy, toned legs and strappy green sandals.
