Leonardo DiCaprioLeonardo DiCaprio is rumoured to be coming to the end of his relationship with model Bar Rafaeli after reportedly spending a whole evening out with friends on the phone to her.

Leonardo is currently in the UK promoting new film Blood Diamond and was spotted at Aura in central London on Sunday night - but he wasn’t partying.

An onlooker told the Mirror: “His friends were having a good time but Leo just sat there looking really glum and texting all night.”

“Then as they were leaving, Leo’s phone rang and he started having a heated conversation.”

When the waiting paparazzi outside the club kicked into action, the onlooker noted: “He was like, ‘don’t you take my picture!’ He was clearly in the middle of something and the last thing he needed was flashbulbs going off in his face.”

A second source close to Leonardo told the newspaper: “He was really into Bar in the beginning but now he’s kinda getting to the end of his tether. He finds her really clingy and being apart because of work causes rows.”

The couple have been dating for just under a year after Leo split from supermodel Gisele Bundchen.
