Sir Mick Jagger will reportedly undergo heart valve replacement surgery after cancelling the Rolling Stones' latest tour.

The 75-year-old is set to have a damaged valve replaced during the operation in a New York City hospital this week, according to an online US news website the Drudge Report.

Sir Mick was forced to postpone the nine-week ‘No Filter’ tour across the US and Canada after doctors told him he was not in a sufficient health condition to go on stage.

The band's world tour officially started in September 2017 with a concert in Hamburg, Germany. The Rolling Stones have since toured across Europe and the UK and they announced shows in the US and Canada in November 2018.

More than a million fans, who have reportedly spent an estimated £200 million on tickets, were due to watch the band at 17 sell-out venues.

But the tour will now be postponed for around a month and the promoters AEG Presents/Concerts West told fans that their tickets will still be valid at the rescheduled concerts.

The father of eight - who is worth an estimated £270 million - was spotted for the first time yesterday since his poor health was revealed during a family outing to the beach in Miami.
