The singer, who reunited with the Gym Class Heroes frontman in April (09) - after their December (08) split, was forced to come clean about her celebrity crushes during an interview on an Australian radio show.

In a game of 'Shoot, Shag or Marry' Perry confessed she would love a bedroom romp with Mayer, over other rockers Benji Madden and Pete Wentz.

She told 2Day FM, "I couldn't marry John Mayer, it'd be so intense. I'd definitely shag the s**t out of him though. I'll go on record saying that."

And she declared that Wentz, who picked McCoy to be a godfather to his son Bronx, was definite marriage material because "he seems to be a good dad".

But Good Charlotte rocker Madden had better watch out - Perry said she would be left with no choice but to shoot him.
