Exclusive Sneak Peek: Miley Cyrus Pranks Boyfriend Liam Hemsworth on 'Punk'd' (VIDEO)
Ever the protective boyfriend, 22-year-old Liam leaps to Miley's defense and is seemingly oblivious to the fact that his "Party in the U.S.A." girlfriend, 19, is behind the whole thing!
The Hunger Games hottie isn't Miley's only victim, however!
Turns out she's got a deviant side!
Of course, we all know Miley is a sweetheart -- especially when it comes to animals. She recently picked up a stray puppy that was abandoned outside of a Walmart and showed off the new puppy on Twitter.
