Demi Moore and Ashton Kutcher are said to be keen to book Britain’s Got Talent star Susan Boyle to sing at their anniversary party.

It is rumoured that the Hollywood stars have offered the Scottish spinster £30,000 to appear at the event.

A source told The Mirror: “Demi and Ashton think Susan is absolutely brilliant, in a fantastically unique and kitsch way.

“Demi joked to Ashton about booking Susan to sing for him. She wanted her to lift up her skirt and flash her knee, the way she did with Piers Morgan.

“And Demi has teased Ashton that Susan would eat him alive. The idea is a cocktail party at home in Los Angeles, the highlight being Susan singing.”
