Chelsea Handler might be willing to speak frankly about her sex life, as we saw in her first memoir, My Horizontal Life, but that doesn’t mean the comedienne has bared all — on tape. After Radar Online claimed they had possession of a sex tape starring Handler, the comedienne went on the record about the story on Chelsea Lately. According to Handler, the film is actually a bit she sent out to casting agents as a 23-year-old: “I would like to say to Radar Online: A) thanks for ruining my surprise Christmas gift to my staff, and No. 2, it was made as a joke. I put it on an audition tape for a comedy club because I’m a comedian.”

Phew. I think Handler’s head would have exploded if she had to admit to having something in common with Kim Kardashian.
