According to an observer, "Jennifer Aniston and Orlando Bloom are attracted to each other like heat-seeking missiles".
The two stars first sparked romance rumors after holidaying at a Mexican resort together last year and then later, when it was said that they couldn't hide their feelings at a charity event at the Los Angeles's restaurant 'Beso' last month.
A source then 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 appeared at the event which was hosted by the restaurant's owner Eva Longoria in order to raise money for the 'Epidermolysis Bullosa Medical Research Foundation'.
The pair were joined by many of Jennifer's close 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 favorite person in the world. She looked like she wanted to grab him and make out with him!".
The pair met in 2003, when Orlando starred opposite Jennifer's ex-husband Brad Pitt in the movie, 'Troy'.
