Watch out world, Miley Cyrus is on a punking spree!

Miley Cyrus seems like such a sweet girl. That is, of course, until she starts punking practically everyone she's ever met! In the latest episode of of MTV's "Punk'd," Miley gets her prank on, first by tricking her boyfriend, Liam Hemsworth, and then by totally fooling her pal, Khloé Kardashian!

Watch Miley Cyrus "punk" her boyfriend Liam Hemsworth and Khloe Kardashian after the jump. 

We first told you about Miley's prank on Liam back in March, but we've now got the extended clip, and OMG, it's even worse than we could have ever imagined. As Miley and Liam walk to their car, she spots two butt-naked people chilling in her vehicle. Liam, a true manly man, gets totally pissed and starts arguing with a police officer who is reluctant to help. Things go from bad to worse when the two naked people stumble out of the car showing more body parts than anyone cared to see.  Just as Liam looks like he's about to effing explode, Miley gently tells him that she's punk'd his ass... and she punk'd it good! Liam is understandably a little pissed, but then he kisses Miley and is all like, "What prank? Look at my hot girlfriend! I don't care about anything else."

Though Miley's first prank was a doozy, the girl still wasn't satisfied. Miley also felt compelled to punk the ish out of her pal, Khloé Kardashian. While Miley and Khloé are relaxing at home, a delivery man stops by and accidentally gets his "junk" stuck in the zipper of his pants. He's literally screaming and writhing in pain, all the while Khloe is trying to calm him down and uhhh, "reduce the swelling." Just as Khloe looks like she's about to faint, Miley tells her she's also been punk'd. Ms. Cyrus, you nasty!
