Heroes star Hayden Panettiere has breast enlargement

Hayden Panettiere got tongues wagging recently, with her new busty appearance sparking rumours that the Heroes star has had a breast enlargement.The 20-year-old actress, who plays secret agent cheerleader Claire Bennet in the hit US series, seems to have increased two cup sizes between appearances at the Teen Choice Awards held in August last year and new photos taken this month. A close friend has confirmed that Hayden's transformation is due to long-awaited cosmetic surgery. "Hayden went from an A cup to a C cup and she couldn’t be happier," the close friend told the National Enquirer. "She’s wanted bigger boobs since she was 17, but the timing and scheduling were just never right. She finally decided to do it right after the holidays." Hayden has also dyed her signature blond locks red, which experts believe may be a way of diverting attention from her plastic surgery. Cosmetic surgeon Dr Youn told the newspaper: "It appears she may have had her hair dyed as a way to attract attention away from a possible breast augmentation. "Her breasts appear to have gone from an A to a C, judging from photos." As well as appearing in Heroes, Hayden is also appearing in three Hollywood films this year and also has a burgeoning music career, releasing her first single 'Wake Up Call' in 2008. Her role as Claire Bennet has seen her take home the Teen Choice Award in 2007 and 2008.
