Simon Cowell's ex-girlfriend thinks his mum wants them to get back together.

TV presenter Terri Seymour - who dated the music mogul for six years until 2008 - has remained close to Julie Cowell but insists she will never reunite with her former boyfriend.

Asked if she still speaks to Julie every week, she said: "Yes, I do. She's actually in LA with my mum at the moment. We're all very close.

"But Simon and I are just great friends. There's no chance of us getting back together. There's No Doubt that Julie would love [us to get back together], but it's never going to happen."

Simon got engaged to make up artist Mezhgan Hussainy in February 2010, and while Terri refused to discuss their relationship, she thinks it will be a "surprise" if they do make it down the aisle.

She added in an interview with Britain's Star magazine: "I'd never discuss his family life - that's for him. I can't discuss it, that just wouldn't be fair.

"I honestly don't know if there will be a wedding. You know Simon could surprise all of us. Who knows."

Despite Terri and Simon ending their relationship three years ago, the brunette beauty thinks she will always be associated with the 'x factor' star.

She added: "I don't think I'll ever be out of his shadow - people still come up to me and say, 'Oh my God, you're Simon's girlfriend!' And I'm like, 'I haven't been his girlfriend for years!' "
