Single star Jennifer Aniston is secretly dating a crewmember on her latest movie. The former Friends star was recently spotted leaving a party at pal Courteney Cox's house accompanied by a hunky mystery man. OK! magazine claims her suitor is Brian Boruma, a grip on Traveling in Vancouver - which Aniston recently finished shooting in Canada. A source says, "They met on the set. He was in charge of moving lights and other heavy equipment. He's actually quite a ladies' man. He's dated actresses before." When asked about a romance with Aniston, Bourma told the magazine, "I don't want to talk about that..." Aniston has been linked with a string of men since splitting from husband Brad Pitt in 2005, but has remained single.
