Diddy is currently on a yacht in St. Barth with a handful of friends and family, but on Christmas day we spotted the shirtless music mogul taking what looked like a very important business call. We're guessing it wasn't to arrange jet ski lessons for his guests...

Diddy was joined by lady love Kim Porter and all of his kids, and when he wasn't gabbing on his cell (or having a pow wow with fellow music mogul L.A. Reid, pictured above), he was using it to snap selfie after selfie -- on a selfie stick, natch! Then again, if we were living it up on a $72 million boat, we'd probably take a few pictures of it too!
