Simon Cowell's former girlfriend Sinitta has threatened to reveal the sex secrets of his famous "harem" during their Mediterranean holidays on his "love boat".
The 49-year old British-American singer posted a message on Twitter that read "Harem - a group of women kept together for the purpose of having sex with one man", which was taken as a threat that she is about to make further allegations about the 53-year old music mogul's private life, the Daily Star reported.
The X Factor judge is known for regularly taking his "harem", which includes former lovers Mezhgan Hussainy and Terri Seymour among others, to glamour resorts.
The 'So Macho' singer has claimed that the 'Syco' boss had got her pregnant in 2009 and that she had a termination, and was determined to take a lie detector test on 'The Jeremy Kyle Show' to prove it.
Meanwhile, Cowell, who is expecting a baby with pregnant gal-pal Lauren Silverman, was seen with a mystery cut on his head when he stepped out for dinner in West Hollywood. (ANI)
