It’s not me! That’s what curvy Mad Men star Christina Hendricks is saying about a topless photo that was leaked online Sunday night after the actress’s phone was hacked. Hendricks’s publicist confirmed that the 37-year-old’s phone had indeed been accessed by an unknown hacker, but that the one topless photo in a cache of pictures was not actually of her. TMZ reports that a barely clad Hendricks is seen in one image in what appears to be a self-taken photo of the actress lounging around at home. Hendricks was picked as Esquire magazine’s 2010 Sexiest Woman in the World. Authorities are investigating who may be guilty of the hacking.
