The actress herself has stated they're real... And to my eye, they look very natural, soft and malleable.... I can spot a fake breast job a mile away... So, either they're real... or it's the best breast job I've ever seen....
Lily Collins is hot, but that picture is probably the worst one of her. ------------------------------------------------------------------- Jordana Brewster
Unless you're referring to her hair color (which, she has admitted, has been dyed red from her natural blonde), I must say I believe you are mistaken. They're real and they're spectacular.
