LOS ANGELES: Jennifer Aniston and Orlando Bloom are attracted to each other like “heat-seeking missiles”.

The Hollywood stars, who first sparked romance rumours after holidaying at a Mexican resort together last year, reportedly couldn’t hide their feelings at a charity event in Los Angeles’ restaurant Beso last month.

A source told America’s OK! Magazine, “They were like heat-seeking missiles. They came together, threw their arms around each other and shared a big hug.”

Jennifer and Orlando partied at the event — hosted by restaurant owner Eva Longoria — to raise money for the Epidermolysis Bullosa Medical Research Foundation. The pair were joined by some of Jennifer’s closest friends, including Courteney Cox and her husband David Arquette, Jessica Simpson and Kate Beckinsale.

An onlooker added, “I saw them in a booth next to each other and Jennifer was looking at Orlando like he was her favourite person in the world. She looked like she wanted to grab him and make out with him!”

The pair have known each other since 2003, when the British actor starred opposite Jennifer’s

ex-husband Brad Pitt in Troy. While Jennifer has seen co-stars like Vince Vaughn since her divorce with Pitt, Orlando just got out of a serious relationship with actress Kate Bosworth.
