12 November 2012George Clooney’s girlfriend Stacy Keibler has allegedly been having secret Botox injections. According to Showbizspy, the actress and model has been using injectables to stay looking youthful and keep ageing lines and wrinkles at bay.However, instead of getting her boyfriend’s seal of approval regarding the treatment, the report claimed Keibler has been going behind Clooney’s back because he hates it when women have plastic surgery. “For a while now, she’s been sneaking around behind George Clooney’s back and getting Botox treatments,” a source told the online gossip magazine. “Stacy thinks she looks pretty good for someone in her thirties and says there are some things George doesn’t need to know. Her Botox is one of them!” Neither Clooney or Keibler have commented on the rumours, so for the moment it seems as though they are merely speculation. Botox is a popular line and wrinkle treatment in the UK that works by relaxing the muscles in the face that contract to cause lines and wrinkles.
