Mick Jagger's new romance is just a 'fling...he is trying to move on', says friend

Pals of Sir Mick Jagger claim his new romance is just a "fling" after he was spotted cosying up to a mysterious brunette just 11 weeks after the death of his girlfriend L'Wren Scott.

The 70-year-old music legend - whose long-term girlfriend L'Wren Scott committed suicide in March - was spotted cosying up to a younger woman in Zurich, Switzerland, last week, but a friend has defended him, insisting he needs to move on with his life.

The close friend said: "Of course Mick is still sad over L'Wren but he is working through it and trying to move on with his life. Yes, he had a fling - he's a red-blooded man for goodness sake. But it's nice to see him enjoying life again. He's on the mend."

Meanwhile, Mick recently returned to the stage with the Rolling Stones but the group omitted their 1966 song Paint It Black - about the death of a lover - from the set list for their first three gigs because it's still highly emotional for the musician.

The haunting track sees the rocker describe a funeral, singing: "I see a line of cars and they're all painted black, with flowers and my love both never to come back."

A source told the Daily Mirror: "The lyrics are very personal to Mick and he didn't feel comfortable singing them so soon after L'Wren's death."

Following the publication of pictures of the Brown Sugar star and the mystery brunette, L'Wren's sister Jan Shane has blasted the rocker.

She said: "And people wonder why L'Wren was so depressed?

"These pictures make me really wonder what Mick is thinking and feeling. His daughter says that he is still heartbroken and so devastated about losing my sister.

"And then you see these photos. He will never change."
