24 October 2011X Factor finalist Kitty Brucknell has admitted to using dermal fillers to smooth out the appearance of her forehead. The 26-year-old, who began having Botox injections earlier this year, told the Daily Mail she was worried her frown lines would turn into permanent wrinkles. The singer said she opted to have the anti-aging treatment after watching footage of herself on stage and realising that she was frowning.Kitty said: "I had an injection before I came on The X Factor. My mum has permanent frown lines. It's a genetic thing. I frown when I'm on stage, and when I look back at tapes of myself I look really angry. "Someone suggested getting Botox and I thought, that's a really good idea." Botox injections aren't the only cosmetic procedure that Kitty has tried. Earlier this year she admitted receiving liposuction surgery, in order to remove six litres of fat, so she could look more like her stage idol Britney Spears.
