L'Wren Scott's sister calls Mick Jagger 'grotesquely disrespectful'

L'Wren Scott's sister, Jan Shane, has blasted at Mick Jagger calling him "grotesquely disrespectful", after it was revealed that the star had spent time with a lover only weeks before the fashion designer's suicide.

Shane, 53, told the Mirror, that the incident revealed the true-self of the 70-year-old Rolling Stones legend who has moved on with as if nothing happened, and feels her sister deserved more respect.

She added that she thinks Jagger was a bigger part of her problems, and she's relieved that Scott doesn't have to deal with him anymore.

Jagger had apparently met the 27-year-old ballerina named Melanie Hamrick, backstage during the Rolling Stones concert in Tokyo, which was 11 days before Scott, 49, committed suicide in her New York apartment.

The singer was also spotted embracing Hamrick on his hotel balcony in Zurich on June 1, and according to the sources "consummated the friendship" during this meeting.
