Jerry Hall says it will be "very difficult" for Sir Mick Jagger when he returns to the Rolling Stones concert tour that was cut short this year following the death of his partner L'Wren Scott.
The Texan model and former wife of Jagger said it was “still tough for him” after fashion designer Scott killed herself in March this year.
The band is set to perform a string of concerts starting later this month after they cancelled their seven-date tour of Australia and New Zealand after her death.
In an interview with the Daily Mail Weekend magazine, Hall said of her ex-husband's return to the tour in Australia: "That's going to be very difficult for him. What a tragedy. She was such a lovely girl and really talented."
In July, Jagger spoke publically for the first time about the death of his partner of 13 years, saying it had been “a very hard year”.
The singer said that he’d received “a lot of support” from family and friends. He said he“got back into it” by working on touring with the Stones in Europe, and doing other things.

Hall said Sir Mick is still a "great friend", and despite their marriage ending, she said: "Actually, we really like each other. We've always been friends."
The 59-year-old told the magazine she thinks Sir Mick is "quite the bachelor", adding: "It probably suits him better not to be married. I think he sees a wife like a candlestick with a snuffer attached - someone to dampen his fun."
Hall said Sir Mick is "super fit" and told the magazine that the rock star was more strict with their children than she was.
Asked about drugs, she said: "That's never been much of an issue. Neither Mick nor I take drugs. He's never been into drugs since I've been with him, which was many years ago."
