'Pretty Little Liars' & 'Young & Hungry' Keegan Allen Crossover: Troian Bellisario's On-Screen BF Appearing on Emily Osment & Ashley Tisdale's ABC Family Series

'A' is about to get hungry. Well maybe not 'A' but a Pretty Little Liars fan favorite is about to get a big helping of Emily Osment, as Keegan Allen is making his jump from one ABC Family show to another. The actor, who plays Toby on the show, and Troian Bellisario's onscreen love interest, is trading in his cop duties in Rosewood for some time rock star time in San Francisco on Osment's comedy series.

The series, which is currently filming its second season, will see Keegan make an appearance in an episode where he will take on the role of Tyler, a hipster drummer who has eyes for Osment's character of Gabi.

Should Spencer be nervous that Toby will leave Pennsylvania for the sunny coast of California? We doubt it, as Gabi definitely has her hands full with guys, as not only does her boss Josh, played by Jonathan Sadowski, have eyes for her, but recurring guest star Jesse McCartney, who plays Cooper, also confessed his love for the chef in the season one finale.

Keegan is only scheduled to be part of the series for one episode, as of right now. He will start filming scenes for it this coming week, with the episode looking to air in the next couple of weeks.

According to Just Jared, this won't be the only friendly face that fans will be seeing during season two as executive producer Ashley Tisdale will also be reprising her role of Logan Rawlings, who shared a little lip lock action with Gabi during an episode last season.

The new season will premiere on Wednesday, March 25 at 8:00 p.m.
