Singer Russell Watson has revealed he has secretly got engaged to his girlfriend despite the 22-year age gap between them.

The tenor proposed to Louise Harris, 25, over Christmas and said the age difference does not matter.

He told Hello! Magazine: "Since we met, I've never seen myself with anyone else.

"I knew how much I loved Louise, how she brought sunshine into my life. I knew I'd spend the rest of my life with her. I guess proposing was solidifying the relationship we already had."

Russell, who has two children from a previous marriage, said proposing "felt so emotional".

He said: "People view the music industry as this big glamorous ball of parties, glitz and fun and it's not.

"In the four years I was on my own, I'd often go home to my empty house and was lonely and sad. To find someone with whom you have a real affinity and makes you laugh is a rare thing."

The 47-year-old, who underwent extensive treatment for a brain tumour in 2007, said the age gap was not a problem.

He said: "On our first night out it didn't pass me by that there's an age gap between us. I thought 'What will we talk about?' But we didn't stop talking from the minute we met and haven't stopped since."
