One of the biggest plastic surgery questions in Hollywood has been whether or not Kate Upton had breast implants. Her breast size is listed at a 34D, and her height is a surprising 5' 10". Given her height, it wouldn't be surprising that was her natural bra size. In this photo, she's showing off her assets at the Mercedes-Benz Fashion Week Swim 2012.
She's scrunching her breasts together to make them look even bigger! Bottom line, if Kate Upton had a boob job, it's one of the most natural looking ones of all time. This type of plastic surgery just doesn't come out this natural.
