A sex tape starring Jonah Hill has been leaked on the net, according to reports.

American TV station Fox News say that a 30-minute video of the tubby actor was posted on the web yesterday. The raunchy footage is said to show a doughy Jonah performing sex acts on two hot dogs and a bag of fries. During the video, the Superbad star is said to look dazed and consumes Orangina and "what appears to be ketchup and chocolate sauce."

If true, the sex tape could prove to be damaging to the young actor's career.
