Simon Cowell: "I was a boxer until I got vain"

Simon Cowell has revealed he used to be a boxer "until I got vain".

"I love boxing," the outspoken American Idol judge, 48, told the Las Vegas Review-Journal in the VIP area of the Joe Calzaghe-Bernard Hopkins fight at the Thomas & Mack Center Sunday, "I was a boxer until I got vain."

Meanwhile, the music mogul's relationship with girlfriend Terri Seymour is reportedly near breaking-point because of his reluctance to have children or commit.

A source said last week, "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 traveling 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.

"Yes she has a great life and wants for nothing but Terri is a simple girl at heart who just wants to be a mum and settle down. No amount of money or fame can ever compensate for that.

"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."
