Rihanna vacations in the Mediterranean with friends

When you have a schedule as hectic as Rihanna's, who wouldn't need a vacation?

But the pop star's Mediterranean yacht trip with some gal pals is looking less and less like a retreat, and more and more like a second job. Rihanna shows off her assistant's broken toe.

(Instagram) Rihanna's itinerary on her trip has been go-go-go, right from the start. She began with a shopping trip in Sardinia, Italy, moved on to jet skis, beer, and a water trampoline in St. Tropez, and most recently parasailed in Cannes. RiRi seems to have found very little time for any actual rest and relaxation.

The "S.O.S." singer has been keeping her fans up to date with her Mediterranean vacation, tweeting and Instragram-ing the trip like it's her job: Rihanna in a bikini, Rihanna in another bikini, Rihanna in another bikini watching the sunset, Rihanna and her friends in bikinis lying on a bed ...

You get the idea. In fact, we're getting so obsessed with her vacation photos, we're expecting a summer 2013 release for "Rihanna's Yacht: The Movie."

One downside, though: The last thing Rihanna probably wanted on this trip, besides adult supervision, was to have her ex Chris Brown on her mind. But, of course, Brown showed up in St. Tropez at the same time, reigniting the wildfire of reunion rumours. Brown's rep has denied them, insisting that he was there with his current girlfriend, Karrueche Tran. We each have our own way of coping with stress.

But Rihanna, next time, may we suggest a good, old-fashioned spa weekend with the girls? No phones allowed.
