Katie Melua is getting married.

The 27-year-old singer is set to wed former World Superbike champion James Toseland - who she has been dating since April 2011 - after he proposed before Christmas, The Sun newspaper reports.

Katie - who was previously in a relationship with Kooks frontman Luke Pritchard - was spotted wearing an engagement ring at Hamburg airport this week.

The 'Closest Thing To Crazy' singer and James, 31, were first set up by Katie's keyboard player Jim Watson last year after he spotted the racing star in the audience of her concert at Sheffield City Hall in Sheffield, North England.

James - who is launching a new career in music after being forced into early retirement following a wrist injury last year - has previously revealed one of the best thing about his new fiancee is that she doesn't care about his success.

He explained: "Katie has been great. She had no interest In Me whatsoever because I was a motorcycle racer. She hadn't heard of me. She wouldn't even know what VALENTINO Rossi looked like.

"It was only because her piano player was such a fan that he kept talking about it on the tour bus after he'd met me. It was nice and a relief for someone so established to be attracted to me because of my personality."
