Simon CowellSimon Cowell’s hectic work schedule is reportedly causing problems with his long-term girlfriend Terri Seymour.

The music mogul turned TV talent show judge has been dating Terri for over five years but has said he’ll never marry or have children with her because he doesn’t want to risk his fortune - and up until now, Terri has been satisfied with that.

But now a source close to model Terri has told the People that as she approaches her mid-30s, she’s having second thoughts: “It really is make or break time. She loves Simon but he’s the most stubborn man in the world to live with. He’s always travelling the globe due to his work commitments and they are hardly ever in the same place at the same time.”

“Terri’s 33 now and really wants kids but Simon isn’t interested. Every time she raises the question he changes the subject.”

“She is worn down by Simon’s attitude towards their future life together. As for his new home, she has had no input on its interior design or choice of furnishings. Every single decision is made by Simon. It’s as if it’s his ultimate bachelor pad.”

“Terri also feels upset and humiliated every time Simon mouths off about his unwillingness to get married or have kids in interviews. She thinks it shows a lack of respect towards her.”

“Yes, she has a great life in many ways and wants for nothing but Terri is a simple girl at heart who just want’s to be a mum and settle down. No amount of money or fame can ever compensate for that.”

Simon’s spokesperson Max Clifford denied any rift between the pair, saying: “I’ve spoken to Simon about this and he and Terri are absolutely fine. They’re as happy as they’ve always been.”
