The British rocker hit headlines earlier this month (Jun14) when he was snapped with the young woman on a hotel balcony in Zurich while the band was in town for a concert on 1 June (14).
One image showed the female companion lean forward and kiss a seated Jagger on the head, sparking rumours of a new romance.
The mystery female has since been identified as 27-year-old American ballet dancer Melanie Hamrick, who actually first met Jagger three weeks before fashion designer Scott took her own life in March (14).
A spokesperson for Jagger has confirmed to Britain's Mail on Sunday newspaper that he and Hamrick were introduced when members of her dance company were given backstage access at the Stones' show in Tokyo, Japan on 24 February (14).
However, sources tell the publication nothing happened between them until they reconnected this month (Jun14).
Reports of Jagger's new fling less than three months after Scott's death angered the designer's sister Jan Shane, who blasted the 70-year-old singer's behaviour.
Shane told Britain's 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 photos - he will never change."
