Sir Mick Jagger has denied hitting on Katy Perry more than a decade ago.

The Rolling Stones Rocker, who has been in a relationship with fashion designer L'Wren Scott since 2001, insists he never ''made a pass'' at the 'Roar' hitmaker, 29, after she claimed he tried to romance her when she was just 18.

A spokesperson for the 70-year-old 'Paint It Black' hitmaker told E! News: ''Mick Jagger categorically denies that he has ever made a pass at Katy Perry... Perhaps she is confusing him with someone else.''

The denial came just hours after Katy, who is currently dating singer-songwriter John Mayer, told Australian DJs Ash, Kip and Littsy on Nova FM in Sydney: ''I actually went to dinner with [Jagger] one time, and he hit on me when I was like 18!''

She added: ''Yeah but that was a long time ago, and since then he's been very kind and I got to sing 'Beasts of Burden' on their stage with him on their tour on The Rolling Stone tour.''

Asked how she rejects men like Mick, she said: ''Well you bring a friend and then they do them.''

The 'Part Of Me' hitmaker took to the stage at MGM Grand Garden Arena in Las Vegas with the legendary rocker in May as part of The Rolling Stones' '50 and Counting' tour.

Shortly after the gig, an excited Katy tweeted: ''Yes, I just did gyrated on Mick Jagger. WHAT?! #Stones50 (sic)''
