I'm a huge fan of the Ashton Kutcher MTV show "Punk'd." So when I saw that Taylor Swift was once Punk'd by Justin Bieber, I had to check it out! He got her good!

Taylor is obviously visiting Justin so they can collaborate on some music. Little does she know what he has in store for her! Watch both videos to get the full prank. Justin told Jimmy Kimmel in a later interview that Taylor is so nice, he just HAD to make her cry!
