Are they or aren’t they? Oscar nominee Leonardo DiCaprio and model Bar Rafaeli – rumored to have gone their separate ways – were back together on Valentine’s Day, when OK! spotted the pair dining at Spago in Beverly Hills. They walked hand in hand over to their table and looked to be genuinely happy and in love,’ an eyewitness says. ‘They sat in front of the kitchen at the middle table where they could watch all the action with the chefs and seemed to be having a great time.’ Of course the couple had plenty to celebrate besides the romantic holiday. Leo, 32, is a Best Actor Oscar contender for Blood Diamond and sexy Bar, 21, has a starring role in the pages of the new Sports Illustrated Swimsuit Edition.
