Leonardo DiCaprio and Sports Illustrated model Bar Refaeli (quite possibly one of the most beautiful couples ever) have split. Sources say Leo broke it off because Bar wanted to take their relationship to the next level and move in together. A friend of Bar’s says, Leo “didn't treat her very well, almost like a second-hand girlfriend." Ouch. The source added, "It could just end up as a break but for now they're doing their own thing."
