Kim Kardashian managed to trick her Twitter followers into thinking she had handed out Justin Bieber's phone number yesterday.
However, the phone number she actually Tweeted was the number fans need to call to save Kim's Brother Rob from being eliminated on the current series of Dancing With the Stars, in which he is currently competing.
In what can only be seen as an all time classic prank, Kim Tweeted to say: "Omg I have JustinBieber's phone #!!! 8008683402! Call him! He's taking calls for the next hour."
Kim eventually gave up the game though and revealed the truth: "Ok guys obviously I'm joking, that's not Justin's #! But seriously call & vote for RobKardashian."
Maybe KK could replace Ashton Kutcher for a new series of Punk'd?!
