New mom Charlize Theron has stunned fans after filming a kinky 'sex tape' with two men decked out in bondage gear.

The Oscar-winning actress donned a lacy night gown for the fake clip, which she shot as a parody of stars such as Kim Kardashian and Paris Hilton who have had their X-rated home movies leaked online.

In the prank video for the Funny or Die website, Theron shows off her comedy chops by ordering her leather-clad 'slaves' to dance and cry out for her.

Speaking into the camera, she jokes, "Oh my God, I'm so nervous. I've never made a sex tape before. I hope nobody sees this that's not supposed to see this."

The Monster star then turns on a CD of creepy music and warns, "Move over Paris and Kim cause I'm into some real kinky s**t," and then hurls liquid over her victims and says, "Charlize Theron is burning you with scolding hot milk! Now for the bleeding."
