Simon Cowell's mother was left stunned at his 50th birthday party by the sex shows put on for the guests.

The music mogul celebrated reaching the landmark age with a star-studded bash at Wrotham Park in Hertfordshire, England, and entertainment included a raunchy cabaret act involving sex toys.

Julie Cowell, 82, and her priest friend sat there opened mouthed when one entertainer appeared on stage dressed as a woman's private parts, before pretending to use an assortment of aids.

Simon's friend and publicist Max Clifford told Britain's Daily Star newspaper: "It was a brilliant party, some parts of it had an outrageously camp theme.

"The funniest thing was seeing Simon trying to explain to his mum, who was there with a priest and some of her friends from church. She asked what it was and he told her it was a sideways mouth and a toothbrush but it was very suggestive and it was very clear what it was supposed to be."
