Chris Rock helped a scorned woman take revenge on her ex-boyfriend during a performance on Saturday night (02Oct10) by calling his cellphone and blasting him with a foul-mouthed rant.
The funnyman was taking part in The Night Of Too Many Stars: An Overbooked Concert in New York to help raise money for an autism charity.
And Rock helped bring in extra funds by auctioning off a bizarre prize - the chance to have the comedian "curse out" a former lover during the show.
An audience member named Desiree paid $20,000 (£13,333) for the honour and she asked Rock to call her ex-boyfriend, who she dumped for posting pictures on Facebook showing himself with another woman.
TV funnyman Jon Stewart dialled the number on a cellphone and handed the device to Rock, who fulfilled his promise by launching into an expletive-laden missive at the man, named only as Jeff, according to GossipCop.com.
Proceeds from the event were handed to the New York Center for Autism and the show will be broadcast on U.S. TV later this month (Oct10).
