Video: Pretty Little Liars' Keegan Allen Previews His Young & Hungry Debut

Avert your eyes, Pretty Little Liars fans! Keegan Allen is spending some quality time with one of ABC Family’s leading ladies this week — and her name is definitely not Spencer Hastings.

TVLine has an exclusive behind-the-scenes look at Allen’s guest spot on Young & Hungry (Wednesday, 8/7c), which finds him playing a hot homeless dude named Tyler.

“He’s a transient that lives in his car, parks underneath [Gabi’s] building and meets her under very interesting circumstances,” Allen explains in the video above. “You could say it has to do with undergarments.”

Adds star Emily Osment, “We go on a date and I don’t realize [he’s] homeless.” (Gee, what could possibly go wrong?)

Hit PLAY on the video above, which offers a first look at Allen’s Tyler in action, then drop a comment: Will you be tuning in for his episode?
