Is it just me or has The Hills star, Audrina Patridge’s, breasts doubled in size?

Audrina, who is in Hawaii on the set of her new movie Into The Blue 2, was photographed on the beach sporting a much fuller bikini. If you compare her recent bikini pictures with the pictures from her Maxim photo shoot, you can tell that she had some work done.

So what do you think did Audrina go under the knife like her Hills co-star Heidi Montag did in 2007 or does the green bikini show a more flattering side of her figure?
