Music mogul Simon Cowell has a strange relationship with his ex-girlfriends. Many people can't stand their former partners but The X Factor judge appears to end every relationship on such good terms that he becomes lifelong friends with all of them.
However, one relationship that shows no sign of improving is between two of Simon's past conquests - 80s pop star Sinitta and former model Jackie St Clair.
Sexy Sinitta was holidaying with 52-year-old Simon in Barbados but decided to jet back to a rainy UK as soon as she found out Jackie would be joining them on the island. The pair first fell out more than 25 years ago and are now said to be barely speaking.
A source told the Daily Mirror: "There is definitely no love lost between Sinitta and Jackie. They don't see eye to eye and so much has gone on their relationship seems beyond repair.
"Things escalated in the past month and now they're hardly on speaking terms. Sinitta thought it best to just leave and save face rather than suffer a holiday showdown."
Sinitta, who had hidden her real age and used a stage age for years, deepened her war with Jackie in 2010 when she threatened to reveal the So Macho singer's real age.
She tweeted: "Jackie St Clair, you are the source of all lies and wrong info. I'm sorry after 25 years you still won't stop harassing and bullying.
"I'm 41 and you 51. At 15 and 25 I was afraid of you. I'm not now! Tell all you know and so will I but please tell the truth!"
At the time Sinitta publicly declared her age as 41 when she was in fact 46.
It sounds like it was a wise move for Sinitta to leave!
