Pop star Katy Perry has had enough of all the media glare and attention.

The American pop star told Us Weekly that she plans to "go into a cave" after the hectic travelling to promote her new documentary Katy Perry: Part Of Me is all done.

"I would like to be in a beautiful unplugged place where there's not a lot going on so I can get back into and hopefully write some good songs," she said, adding that she could not wait to "take these damn extensions out of my hair and fill my head again".

Perry will be in Singapore on Sept 23 for the SingTel Singapore Grand Prix.
