Irish rocker Bono has been soaking up the sun with top music star Will.i.am -- sparking rumours they are set to collaborate once more.
The Black Eyed Peas frontman is the latest of Bono's A-list pals to jet to the south of France to keep him company as he recovers from his recent back troubles.
The U2 singer has had regular hush-hush visits recently from VIP friends, including Rod Stewart and Lance Armstrong.
The Dublin star (50) and his family have been holed up in their Eze villa for the past month, while he recuperates from his serious spinal surgery last May.
The Herald can exclusively reveal that his most recent impromptu visitor was concerned pal Will.i.am (35).

Bono invited the top US singer-producer to visit him after hearing that Will.i.am was performing an exclusive DJ set in nearby St Tropez last week.
The singer, who was recently linked to Cheryl Cole, is rumoured to have been paid a mesmerising €100,000 for a two-hour set at a private party in the exclusive Byblos nightclub.
A source close to the singers revealed: "Will.i.am hates helicopters but he willingly jumped on one to spend a few hours with Bono. They've been friends for quite a number of years and have loads in common aside from music.
"Obviously Will.i.am produced a few tracks on the last U2 album, so it's no surprise that their latest meeting has prompted speculation that he and Bono could be soon ready to hit the studio together again."
Bono is expected to return to the stage in Turin on August 6.
