Shirtless Leonardo DiCaprio has been relaxing with friends all week in Ibiza, Spain. On Tuesday, Leo took to the water on a Flyboard, which is similar to a wakeboard and is connected to turbines and water jets (don't worry, it had us scratching our heads too). Today's activities featured lounging in the sun, smoking, and whizzing around on a Jet Ski. Leo has been vacationing overseas with his new girlfriend, German model Toni Garrn. Things seem to be getting serious for the couple, who showed PDA on a boat before slipping into swimsuits to hang out by the pool earlier this month.
