Brook: 'Lesbian scenes were difficult'

Kelly Brook has admitted that she found it "difficult" to film lesbian scenes for her new movie.

The model and TV presenter revealed that she had to kiss pornographic actress Riley Steele in Piranha 3D, reports The Sun.

Brook said: "It was really difficult. Holding your breath while making out with someone as hot as Riley Steele. I had to learn to hold my breath for a very long time."

The 30-year-old said that the pair had to have "a lot of practice" before filming the scene.

Riley added: "It's not work when you get to kiss Kelly Brook. She's so hot. Doing it underwater did make it a bit more difficult but I'm not complaining."

Brook previewed a clip of the scene at Comic-Con and told the audience: "It's a lot longer in the film. It goes on for quite a long time."

Piranha 3D opens in the UK on August 20.
