Katy Perry lip syncs! Well... not to her own songs, but to Carly Rae Jepsen's "Call Me Maybe".

The soon-to-be ex Mrs. Russell Brand hit up the Coachella music festival last weekend with some pals, and she decided to channel her silly side and make a parody of the breakout song. At one point, she even declares her love for Justin Bieber!

Wait, how is Bieber involved, you ask? Well, the "Boyfriend" singer is actually Jepsen's career mentor. Is there anything the Biebs doesn't have a hand in?!

Now that Katy P is a single lady, we bet a lot of guys will call her... maybe!
