Katy Perry Says Mick Jagger Hit on Her When She 'Was like 18'; Mick Rep Says Perry Is 'Confusing Him With Someone Else,' Who? Don Knotts?

Katy Perry says Mick Jagger "hit on me when I was like 18 or 19," but says "he's been very kind since." Mick Jagger invited Katy Perry to sing "Beast of Burden" with the Rolling Stones on a 50th anniversary tour show in Las Vegas in May.

Katy Perry told an Australian radio station that Mick Jagger, the legendary singer of the Rolling Stones, hit on her when she was singing backup on one of his songs. Mick, who is 41 years older than Katy Perry. is denying the incident.

Katy Perry told Novafm's morning show "I actually went to dinner with him one time, and he hit on me one time when I was like 18 (or 19)."

Katy Perry added "But that was a long time ago, and since then he's been very kind - I got to sing 'Beast of Burden' on stage with the Rolling Stones."

In her pre-fame days, Katy Perry worked as a background vocalist to earn "Taco Bell money."

Katy Perry, who just turned 29, was promoting her new album, "Prism," on Australian version of "The X Factor." She said she was working on background vocals for Mick's 2004 single "Old Habits Die Hard." Yes, old habits die hard, in "Stray Cat Blues," Mick sings "I can see that you're 15 years old, but I don't want no ID." "Old Habits Die Hard" wound up on the soundtrack of the movie "Alfie."

One of Mick Jagger's representatives told the Daily News that the Rolling Stone singer "categorically denies that he has ever made a pass at Katy Perry. Perhaps she is confusing him with someone else."

Mick Jagger is very recognizable, although ever since Spy magazine's "Separated at Birth" featurettes, I still can't get the image of him and Don Knotts out of my head.

Katy Perry knew the music business even at that young age, she said "You bring a friend and then they do him. You sacrifice your friend."
