Taylor Swift Gets Punk'd By Justin Bieber!

Justin Bieber is taking over Ashton Kutcher's role as prankmaster in the first episode of Punk'd.

The "Baby" singer who was originally rumored to be the permanent host of the show, will only be guest hosting for one episode.

He'll be pranking one of his good friends, Taylor Swift. We wonder how the 17-year-old pop star pranked the country cutie. Was Selena Gomez in on the fun?

Seems like the two are pretty close since they are also rumored to be working on a song together.

After seeing the two sing "Baby" at Taylor Swift's concert, fans have been begging for more collaborations between the two, and this new song might just be the next Hollywood hit!

Songwriter Kuk Harrell tweeted:

@taylorswift13 You and Justin Killed that writing last night!!! SMASH!!!!!!

Wow!! Got to see @justinbieber & @taylorswift13 write a song together last night!! SMASH!!!! SMASH!!! SMASH!!! Let's do it again Yall!!!

With all this buzz, we can't wait to hear what the duo has in store for us!
