Despite being the face of multiple fashion campaigns and starring on British TV and stage, model/actress Kelly Brook isn’t ready to rest on the laurels of her 32-E’s. That’s why the gorgeous 30-year-old, 5-foot-8 stunner is skinny-dipping with porn star Riley Steele in director Alexandre Aja’s eagerly-anticipated Piranha 3-D.

She tells U.K. site The Mirror:

I don’t think I’ll be getting any Oscars for it. It’s about a lot of fish that eat a lot of buff boys and big-boobied girls. It’s all set during spring break.

It’s not a B movie – it’s the biggest-budget horror movie ever made and it’s in 3-D. There’s Oscar-winning actors in it like Richard Dreyfuss – and a lot of porn stars. I fit in somewhere between. I have a lot of scenes with the porn star Riley Steele – including nude underwater scenes.

Steven R McQueen from The Vampire Diaries plays the lead and he clocked that I was getting more daily pocket money than him. So I said, “I think my body will work a bit better in 3D than yours, mate.”

While Brook is happy to use her God-given gifts of T&A to pay her rent, she sometimes gets bummed over the typecasting.

She explains:

I was sitting in a restaurant and the director [Alexandre Aja] came up and said, ‘I think you’ll be right for this movie I’m doing,’ and then when I read the script, I thought, ‘Oh yeah, thanks, it’s not really a compliment.’

Personally, I’m tired of being typecast as someone who has to do a thankless 9-to-5 job to pay my bills.

Who needs Oscar when you have Golden Globes?
