Darren Criss and Lucy Hale pulled double duty Sunday night -- both co-hosting the 2013 Teen Choice Awards and sharing a behind-the-scenes look at the star-studded event by posting photos on Instagram and Facebook for fans.

Criss, 26, and Hale, 24, seemed to amuse themselves as they posed for a variety of photographs, both individually and together before hitting the stage.

"Almost done with rehearsal! #teenchoice," the Pretty Little Liars star posted with some friends backstage via Facebook. The brunette beauty also shared one of her goofing off with Criss, in which she wraps her arm around his neck while rehearsing. She even gave fans a sneak peek of her glam look, revealing the white Houghton dress she would be wearing for her red carpet arrival.

All fun and games, the Glee star kicked it up a notch when he posted a so-called "prom photo" of the two via Instagram. "Prom photo? #teenchoice @lucyhale #dayinthelife," he wrote.

He also added a funny video pretending to talk to some famous pals in the audience, which turned out to be just their paper seating assignments. "You always know how to make me laugh! Selena [Gomez], Demi [Lovato], thanks for sitting next to me," he said. "You really know how to make me feel at home. Sandra [Bullock] do you mind? I'm trying to have a conversation here," he joked.

The rehearsals seemed to be well worth it too. The actors later won big, with ABC Family's Pretty Little Liars bringing home seven surfboards, including Hale winning for Choice Summer TV Star: Female. Criss' FOX comedy Glee took home four, including Choice TV Comedy.
