On-again off-again couple Leonardo DiCaprio and Bar Refaeli have called it quits once more, sources confirm to PEOPLE.
"They're taking time off for the time being, they've split," says a source close to the actor. "It could just end up as a break but for now they're doing their own thing."
That much was certainly apparent over the weekend as the Israeli-born Sports Illustrated swimsuit model, 23, walked the red carpet at Hollywood Life's 11th Annual Young Hollywood Awards solo, refusing to speak about DiCaprio.
According to a Refaeli source, the model's desire to get serious may have caused the actor to have doubts about their relationship. "She wanted to move faster than he did, she wanted to move in together," the source says, "so he broke it off."
A source in Refaeli's circle says DiCaprio "didn't treat her very well, almost like a second-hand girlfriend."
