Model-turned-actress Jenny McCarthy gave members of her studio audience an eyeful while pre-taping her raucous Friday night chat show earlier this week (ends17May13) by flashing her boobs.

Guest Lil Jon dared the former Playboy pin-up to bear her breasts for the cameras and she duly obliged.

He said, "I will give you $100 if you show off your t**ties to everyone over there..."

MCCarthy stood up, lifted her top and her black bra and flashed away - and then grabbed a grinning Lil Jon's $100 bill.
