Demi Moore has sensationally split up with younger boyfriend Ashton Kutcher - after discovering that their eight month relationship was a practical joke for his TV show Punk'd'.
Eye witnesses claim that Kutcher, 25, was forcefully evicted from Moore's Hollywood mansion by bodyguards after revealing the stunt.
"Ashton brought a bikini clad blonde into the lounge, shouted You been punk'd, Demi!' and proceeded to receive oral pleasure from the other gal," said one excited onlooker. "You should have seen Demi's face."
In the course of the last eight months, prankster Kutcher convincingly played the hopelessly love-struck romantic, taking Moore out for expensive candlelit dinners and exotic foreign holidays.
"She's rich, beautiful and famous, but let's face it, she's a little bit short in the brains department," laughed Kutcher. "I mean, you're going out with the creator and presenter of Punk'd' and you don't even think to yourself hey, maybe I could be getting punk'd here?' Wakey, wakey Demi, rise and shine!"
Moore, 41, refused to comment on the issue although one of her close friends said she was devastated'.
"Basically, Demi got punked bad," she added.
