Katy Perry would love to be in a musical

Newly-single Katy Perry has big plans for a year-long break from touring.

Russell Brand filed divorced papers in LA yesterday and in a shock career change, 27-year-old singer Katy is said to be gearing up to hit the silver screen - and is already making progress as an actress.

'Katy wants to be a movie star more than anything and has been taking acting lessons for the past year,' says a source.

'[Her] ideal role is to play a part in a movie musical like Chicago, Nine or Rock Of Ages, where she can sing and act at the same time.'

'Her agent has been pursuing a one-off role for her as a dying/injured girl on Grey's Anatomy, so it's looking likely she'll be doing that show next year.' 

Katy was keen for 36-year-old husband Russell - who made the transition from comedian to actor in 2007 - to get involved in her Hollywood career.

But even if they do stay 'good friends', will she still want him to star as her leading man in a major movie?

'She'd love to be in a rom-com opposite Russell - and has asked both her agent and his to find a part that would suit them,' the insider told Buzz magazine earlier this year.

'Failing that, she's even working on writing a film for them to star in together.'

Mmmmm.
