As we reported yesterday, Bono was treated last Wednesday at the Princess Grace Memorial Hospital in Monaco after complaining of chest pains. The U2 man, who recently took in a massive payment from his 2009 investment in Facebook, was examined by a leading heart specialist and was instructed to get plenty of rest. Bono was spotted two days later in the hip Saas Cafe with his wife Ali Hewson, Julian Lennon and John Rocha.

This is Bono's second case of health issues in the past year. In 2010 Bono was forced to cancel U2's Glastonbury appearance after injuring his back, requiring urgent surgery.
