After posing nude in her last movie called 'Three', British actress Kelly Brook feels like she hadn’t enough from the sex image domain. So her goal of getting even sexier on the screen was achieved when she romped with former porn star on the set of her new movie.

She was wearing a red bikini while Riley Steele was with her hands all of the British actress in Piranha 3-D - a remake of the 1978 comedy horror.

And it seems like this wasn’t just a coincidence. According to Steele "She's like 'I have so many questions for you'. She wants to know all about my porn career."

In the movie, Kelly plays at college girl spending the summer in Lake Victoria and becomes pals with Riley's character, a stripper called Crystal.
