In April, there was word that Simon Cowell and Terri Seymour were having problems in their relationship 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.”

Now after dating for 6 years, the couple have decided that it is time to call it quits. Simon has reportedly walked out on Terri following repeated trouble over her insecurities.

A friend of Simon’s recently 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, American Idol 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.
