Russell Brand wants to leak sexy pictures of Katy Perry.

The 'Get Him to the Greek' star is planning revenge on his fiancee after she dubbed him "Bridezilla" over his enthusiasm for their marriage plans and even posted a picture of him on twitter wearing a wedding dress.

He joked: "Katy, that little cow, keeps calling me a bridezilla. Travis Cocker wrote, 'Just Say Yes,' the single we're releasing from the film, and for that, one of the costumes I wore was a wedding dress. I sent Katy a picture and she put it on the internet and goes, 'Oh look at him he's obsessed with this wedding.'

"I'm trying to think of a way to get revenge. Let me tell you there are photos of her on my phone that could go nuclear!"

However, the British funnyman is wary of revealing the sexy snaps because he is scared of the repercussions.

He added to MTV News: "A man has to be respectful. I'm so tempted but I feel I'm going to need my testicles for the future."

It has previously been claimed Katy is planning to wear a daring midriff-baring wedding gown and though Russell doesn't want to upstage his bride, he has promised his attire for the big day will be no less shocking.

He said: "I think it would be unfair to say this day is all about me.

"I'm going to wear a tuxedo and a top hat with no pants and I'm going to paint my penis with lipstick. This is her day. It's not about those mental images."
