Hope you’ve been practicing that break dance fighting, Ryan Guzman. The Step Up: Revolution star just began filming as the newest Pretty Little Liars hunk and judging by showrunner Marlene King’s tweet, he’s already in danger...

“Beware @ryanAguzman. Nothing is as it appears to be in Rosewood,” tweeted Marlene. How nice of her to provide fair warning! Though, we can back her up on that. Guys with rock-solid abs don’t have the best of luck in Rosewood. Just ask Jason...Oh wait, you can’t. Because he is missing and might be dead!

At least it sounds like Ryan’s character won’t be totally defenseless. He will be playing Rosewood’s hot martial arts instructor, Jake. And potentially a new love interest for Aria? (Though that second point won’t save him from Fitz’s death glares.)

"Its gunna be interesting teachin @lucyhale martial arts for our scenes," Ryan tweeted. "Let's see if I can get her to do a judo hip throw." Better focus on honing your own training, Ryan - if only to fend off the legions of Ezria fans. According to writer Bryan Holdman, they’re gonna hate you.

Jake will be popping up in the second episode of the fourth season, “Turn of the Shoe.” Are you excited to meet Jake? Any bets on how long he will be sticking around? Let us know in the comments below!

Catch the next episode of Pretty Little Liars on Tuesday, June 11, 2013 at 8 p.m. ET/PT on ABC Family.
