Miley Cyrus was chief prankster in Punk'd this week, as she set up Kelly Osbourne, Khloe Kardashian and her boyfriend Liam Hemsworth.

In what seemed to be a very naked episode, Miley and the Punk'd team managed to trick Liam into thinking that some doggers had run into his car while he left it unattended and started shagging on his back seat.

"You have no underwear on? Get your balls off the seat. This guy clearly doesn't want your weiner all over his nice Mercedes," Liam watched the police officer tell the brazen bonkers, before he was told that he could be charged for the criminal offence as it was taking place in his car.

Miley's prank-attack on Kelly Osbourne was also pretty man-tackle themed, after she invited Kelly over to her place for some takeaway, and the delivery boy had to use the bathroom.

Miley and the takeaway dude then pretended that he'd got his plums horrifically stuck in his fly as he was doing up his zip, and then the fake emergency services on the phone told Kelly O to "take a good look at the testicles and tell me what colour they are."
