Some people will go to any lengths to avoid talking to an ex. US singer Katy Perry resorted to disguising herself as a goth, a geek and a hippy at the Teen Choice Awards.

Perhaps the fiance of Russell Brand was trying to avoid a row over her latest lyrics which have a right pop at Travis McCoy.The lines in Circle The Drain - reportedly about the Gym Class Heroes frontman - include: "You could have been the greatest/But you'd rather get wasted/"You fall asleep during foreplay/cause the pills you take are more your forté.

"I'm not sticking around to watch you go down/Wanna be your lover/Not your mother."
