The British rocker was photographed with an unknown brunette on a hotel balcony in Zurich, Switzerland while the band were in town for a concert on 1 June.
In one picture, the unidentified woman appears to lean forward and kiss a seated Jagger on the head.
Jan Shane, sister of the tragic fashion designer who took her own life in March, has now spoken out about the reports and questioned Jagger's behaviour.
Shane tells the Sunday Mirror newspaper: "These pictures make me wonder what Mick is really thinking and feeling. His daughter says that he is still heartbroken and devastated about losing my sister, and then you see these these photos - he will never change."
