On-again off-again couple Leonardo DiCaprio and Bar Refaeli are off once again, sources confirm to PEOPLE.

The 23-year-old model, who covered this year’s Sports Illustrated Swimsuit, reportedly made her split from the 34-year-old Titanic star official at last weekend’s 11th Annual Young Hollywood Awards stag.

“They’re taking time off for the time being, they’ve split,” says a source. “It could just end up as a break but for now they’re doing their own thing.”
