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.

Cowell, who recently split from the 33-year-old TV presenter after five years together, has reportedly splashed out on a property for her in Hollywood, California.

The music mogul, who has always ruled out the possibility of having children, has hinted he may be ready to become a father and has even started picking out names.

According to The Sun, sources have revealed London law firm Carter Ruck, which gave Shetty the legal advice and guidance in the aftermath of the British Celebrity Big Brother race scandal, has sued her management company Cine Entertainment for unpaid bills worth $20,000.
