Simon Cowell And Girlfriend Terri Seymour Reportedly Split

The 48-year-old music mogul is believed to have walked out on Terri, 34, following a blazing row over Terri's insecurities, and he has now ended their six-year relationship.

A friend of Simon's told Britain's Star magazine: "He told me he is tired of Terri's insecurities. They lead separate lives, and that's how he likes it, but lately she has turned up unannounced at events he is at."

"Just recently, she was meant to be working on a red carpet as part of her presenting job for US TV show 'Extra'. But instead she turned up at a party Simon was at with Ryan Seacrest. Simon wasn't happy and felt like she was checking up on him."

After the argument, 'X Factor' judge Simon is reported to have jetted off to his St Tropez villa with friends - including his ex-girlfriend Sinitta and celebrity hypnotist Paul McKenna - leaving Terri behind.

In April, it was claimed Simon and Terri's relationship was at breaking point due to Simon's reluctance to settle down and start a family.

A source said at the time: "Terri is worn down by Simon's attitude. She feels upset and humiliated every time Simon speaks about his unwillingness to get married or have kids."
