L'Wren Scott's brother Randy Bambrough backed Mick Jagger on the new romance following his estranged sister Jan Shane's blasting remarks against the singer.
While talking to the Mirror, Bambrough said that Scott's suicide had nothing to do with the 70-year-old singer's alleged 'backstage' meeting with his new lover Melanie Hamrick, and he thinks that the accusations were "ridiculous".
He added that her sister was really important to the Rolling Stones frontman, and his love for Scott should not be debated.
Last week, pictures of Jagger with the 27-year-old ballet dancer on a hotel balcony had emerged, which, according to sources was the first time the pair had "consummated their friendship".
