Where's Jamie Hince? We'll tell you one thing -- he's not on the Italian coast partying on a yacht with his wife!

A bikini-clad Kate Moss was partying the day away aboard a yacht and was noticeably without her rocker husband on Wednesday. However, she was with a number of fine looking friends who seemed to be enjoying living the fabulous life off the coast of Italy.

Split rumors first circulated this summer that the 41-year-old supermodel was having marriage problems with The Kills rocker, but it looks like Kate doesn't have a care in the world. Wearing a $500 black bikini by Eres (which seemed to slip off at one point), the model kicked back on the yacht with a glass of wine and some pals, including British TV presenter Richard Bacon and his wife Rebecca McFarlane.

Kate and Jamie were married in a celeb-studded wedding in 2011, but have not been photographed together since attending a charity bash in Sao Paulo, Brazil, in April. So things are not looking good in the long-lasting love department ...

If Kate's heartbroken -- she's doing a great job of hiding it -- and showing off that legendary body at the same time!
