LEONARDO DiCAPRIO and BAR REFAELI are in the middle of a split riddle, amid online rumours they've ended their three-year relationship.

Sources claim the couple has agreed to take a break after falling out over the future of their romance.

The Israeli supermodel has apparently grown tired of Leo's reluctance to commit, according to friends who say: "She wanted to move faster than he did, she wanted to move in together."

But the couple have since been caught together on a late night shopping spree in Los Angeles on Monday night, disputing the break up claims.
