Sir Mick Jagger will undergo heart surgery this week after dates on the Rolling Stones' North America tour were postponed.
Sir Mick, 75, is to undergo surgery this week in New York to replace a heart valve, according to reports.
The surgery is said to involve placing a stent in the singer's heart.
A spokesman for the British band in London declined to comment on the reports.
The band announced on Saturday it was postponing all dates on its tour of the United States and Canada to give Jagger time to receive medical treatment.
It did not specify what treatment Jagger needed but said he is expected to make a full recovery.
The North American tour had been scheduled to run from April 20 until June 29.
Sir Mick was photographed on Sunday in Miami Beach, Florida on the beach with his girlfriend, ballet dancer Melanie Hamrick, their young son, and daughter Georgia May, one of his seven adult children.
The singer has not explained his medical issue but told fans in a tweet on Saturday that he would be "working very hard to be back on stage as soon as I can."
Representatives for Jagger in the United States did not return requests for comment.
