Mick Jagger's womanising ways contributed to L'Wren Scott's depression, her estranged sister has said. The accusation comes a week after the rocker was pictured enjoying a rendezvous, with a Scott look-alike, in Switzerland.
Jagger's liaison took place less than three months after the suicide of Scott, his partner of 13 years.
"And people wonder why L'Wren was so depressed?" said Jan Shane, 53, who hadn't spoken to her adoptive sister for six years and who was not invited to the funeral.
Photos show Jagger looking relaxed and intimate with the younger brunette on his hotel balcony in Zurich. According to reports, Jagger spent two days with the woman he met at a nightclub.
The Rolling Stones frontman was there with his bandmates performing, having resumed their world tour last month. They put the tour on hold following 49-year-old Scott's suicide in March.
"These pictures make me really wonder what Mick is really thinking and feeling," Shane continued in an angry outburst to The Mirror.
"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."
Friends of Jagger told The Mirror it was not his first fling since Scott's death.
They have also defended the 70-year-old.
"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."
Another friend said: "Some men drown their sorrow in drink. Mick doesn't drink much but he drowns his sorrows in women.
"He has reverted back to his old ways. This is how he deals with things, even in his 70s. Through good times and bad, the thing that never changes is Mick's love for women. Sex is like a coping mechanism for him."
Jagger has previously admitted to having a "bohemian view" of relationships.
"I don't really subscribe to a completely normal view of what relationships should be. I have a bit more of a bohemian view," he said.
Earlier this year, Scott's long-term housekeeper said her employer was aware of Jagger's infidelities throughout their relationship.
"She knew there were other women, but she accepted it to be with him," the housekeeper, Lupe Montufar said.
Scott, whose fashion label was in financial strife at the time of her death, left her $9 million estate to Jagger.
After she was found in her New York apartment on March 17, Jagger said he failed "to understand how my lover and best friend could end her life in this tragic way".
He added: "We spent many wonderful years together and had made a great life for ourselves. She had great presence and her talent was much admired, not least by me. I have been touched by the tributes that people have paid to her, and also the personal messages of support that I have received. I will never forget her."
