06 September 2010Teen star Miley Cyrus has been hitting the headlines recently following her breakup with boyfriend Liam Hemsworth, but photographers have also been speculating over whether she's had Botox. The 17-year-old actress and singer, who rose to fame starring in the Disney Channel sitcom Hannah Montana, was photographed on the way to her surprise performance with Justin Bieber on Tuesday with a noticeably puffy face. This led celebrity gossip site DailyFill to speculate Miley may have had non surgical treatments such as Botox or dermal fillers.Miley was also previously rumoured to have had a boob job to boost her career, but these claims were never substantiated. Entertainmentwise reported earlier this year that she was intent on getting a breast enlargement and was trying to persuade her parents to sign the consent forms required for under-18s. DailyFill said: "It pains us to think that 17-year-old Miley Cyrus has already started to alter her appearance like this. Older women use collagen and botox to smooth out wrinkles; it's not meant for teenagers to use like makeup!" Impressionable teenagers are discouraged to look towards cosmetic surgery solutions until they are old enough to make the decisions for themselves. Reputable clinics and surgeons will not treat patients under 18 unless they require corrective plastic surgery. DailyFill does not believe Miley had treatments as a direct result of her split. The website reports that Miley is dealing well with the breakup, and has already been rumoured to have dated two of her co-stars from LOL, Adam Sevani and Douglas Booth.
