Christina Hendricks has fallen victim to phone hacking, with several pictures of her posing in her underwear leaked on the internet.
But the Mad Men star's representative has denied that a topless picture, which doesn't show her face, is of the actress.
Christina's rep told E! News: "Christina's phone was in fact hacked and photos were stolen.
"The proper authorities have been contacted in hopes of rectifying this situation. The topless image is fake and not an image of Christina."
One picture shows the 36-year-old curvaceous red head posing in her bra, with another picture showing her wearing a basque and frilly knickers. There is also a snap of the star with no make-up and glasses, wearing just a t-shirt.
I Don't Know How She Does It co-star Olivia Munn was also reported to have had her phone hacked and nude pictures leaked.
But she laughed off the rumours, tweeting: "If you ever hacked my phone, these are the photos you'd find", followed by pictures of a kitten and a baby.
