DHAKA: Rolling Stones frontman Mick Jagger said he was ‘struggling to understand’ girlfriend L’Wren Scott’s apparent suicide as it emerged the fashion designer’s business was grappling with multi-million-dollar debts at the time of her death.

Jagger, who was reportedly heading back to New York after the Stones cancelled the opening leg of an Australian tour that was to have begun on Wednesday, described 49-year-old Scott as not only his lover but his best friend.

‘I will never forget her,’ Jagger, 70, wrote in a blog post on his website, a day after Scott was found dead at her luxury New York apartment after her suspected suicide.

‘I am still struggling to understand how my lover and best friend could end her life in this tragic way,’ Jagger wrote under a post entitled simply ‘L’Wren’, featuring a black and white photo of the former model, reports The Straits Times.
