Washington, Dec 6 : Music mogul Simon Cowell has been given a rating of “11 and three-quarters out of 10” for his performance in bed by his pop star ex-girlfriend Sinitta.

Sinitta, who is an American actress and singer, once dated actor Brad Pitt and had a brief romance with Cowell in the 1980s.

She is presently working alongside Cowell on his U. K. reality TV show ‘The X Factor’.

The 42-year-old made the claim that Cowell, who split from girlfriend Terri Seymour in September this year, is no disappointment when it comes to sex.
