U2 frontman Bono was taken to hospital last week following heart palpitations while holidaying in the South of France.
Reports have just surfaced that the singer, 51 was rushed by his wife to hospital after complaining of chest pains last Wednesday (August 17th.)
Bono, real name Paul Hewson, was discharged after a few hours at Princess Grace Memorial Hospital and ordered to take plenty of rest.
After being checked out by a heart specialist the rockstar was given the all-clear.
The singer was spotted relaxing in Monaco the following day with wife Ali, plus friends Julian Lennon and designer John Roca, the Irish Independent reports.
The vocalist was staying at the luxury mansion he co-owns with U2 guitarist The Edge in Eze-sur-Mere, just outside of the tax haven of Monaco.
The hospital visit follows a separate health scare last year when Bono injured his back while training on tour, requiring emergency surgery.
U2 had to postpone their tour commitments, playing their Glastonbury booking twelve months after the planned date.
The band recently concluded their mammoth 360° world tour in Canada after playing to over seven million people in 30 countries.
The record-breaking jaunt set is now the highest grossing tour by a band, making $736,137,344 (£445m.)
Bono hit the headlines earlier this week when it was reported that his stake in social networking site Facebook had quadrupled in value to nearly $1bn (£604m)
The U2 frontman’s investment firm Elevation Partners bought a $210m (£127m) stake in the site in November 2009.
After another investor sold his stake however, Elevation’s share of the company skyrocketed to $975m in value, a colossal 400 per cent increase on the initial investment.
