When Taylor Swift was invited over to Justin Bieber's place to help him write a track for Selena Gomez, she probably didn't expect what was to happen next.

 

Justin Bieber, who has replaced Ashton Kutcher on Punk'd, was to trick Taylor Swift into believing she had set fire to a boat, ruining a wedding.

Pop star Justin invited Taylor over to help write a song with him before asking if she would set off some fireworks.

Apparently, one of the fireworks 'accidentally' landed on boat which was hosting a wedding party, setting fire to it and meaning the guests, who were actually actors, had to flee by swimming to shore.

An insider explained that the beauty didn't cry but was very freaked out and said 'OMG I'm so sorry!' before Justin revealed that she had been Punk'd prompting Taylor to start laughing and ask: "How could you do this to me?"

Luckily all was forgotten later as Justin and Taylor performed Baby together in the Staples Centre in LA.
