Sir Mick Jagger said on Friday he was "on the mend" after undergoing surgery that caused postponement of the Rolling Stones' planned North American tour.
The 75-year-old singer reportedly underwent heart valve replacement surgery in New York earlier this week.
Sir Mick and his representatives did not provide details of the surgery but said it had gone well.
"Thank you everyone for all your messages of support, I’m feeling much better now and on the mend - and also a huge thank you to all the hospital staff for doing a superb job," Sir Mick wrote on Twitter.
His US publicist said the treatment had been successful and that Sir Mick was expected to make a full recovery. His need for surgery forced the Rolling Stones last weekend to postpone its entire 'No Filter' North American tour that had been due to start later this month.
A statement from the group on March 30 said: "Mick has been advised by doctors that he cannot go on tour at this time, as he needs medical treatment."
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.
Billboard magazine, citing unidentified sources, said the surgery involved the replacement of a heart valve by going through Sir Mick's femoral artery.
The procedure, known as transcatheter aortic valve replacement, or TAVR, is an increasingly widely-used alternative to surgical valve replacement that requires the chest to be opened. TAVR typically allows for shorter hospital stays and quicker recovery times.
The Rolling Stones tour is now expected to begin in July, Billboard said.
The father of eight - who is worth an estimated £270 million - was spotted for the first time last week since his poor health was revealed during a family outing to the beach in Miami.
The rock veteran was pictured smiling alongside his model daughter Georgia Jagger, 27, and two-year-old son Deveraux.
Sir Mick - whose eldest child, Karis Jagger, is 48-years-old - is also a grandfather to five children and, in 2014, he became a great-grandfather for the first time.
