11 November 2011Australian singer and actress Kylie Minogue has responded to suggestions that she has gone back to using Botox to help maintain her youthful appearance. The star was pictured attending an event in London earlier this week, which led to rumours circulating that she had once again turned to dermal fillers to banish lines and wrinkles. In an interview last year Kylie admitted she had used the product in the past but said had no intention of doing so again.She turned to social messaging service Twitter to vent her frustration at the "annoying" reports, which she dismissed as a "load of rubbish". Kylie said: "So, I have been filmed out in public the last three nights and suddenly it is 'reported' I cannot move my face?" The 43-year-old was photographed at London's Royal Opera House where George Michael had put on a dinner and charity concert. The star has said that her good skin is now the result of using anti-ageing moisturiser cream.
