Ed Sheeran Predicts Grammy Awards 2013 Success For Fun.

The 'Lego House' singer believes he will lose out in the Song Of The Year category.

Ed Sheeran has admitted he doesn't think he will win Song Of The Year at the Grammy Awards 2013.

The 'You Need Me, I Don't Need You' star spoke to MTV News ahead of this weekend's show and said he thinks Fun. will take home the top prize for their hit 'We Are Young'.

"I'm pretty sure Fun. will win. I think that song is great," he said. "I think there was no other song bigger than that last year, and if you were gonna go by that, they'll win, but I'm usually good at calling these things."

The British star will also be performing on the night alongside Sir Elton John , but admitted the thought of making a speech is a far worse prospect than the performance.

"I'm most nervous about that, having to do a speech — if I get to do a speech," he added. "I always leave people out of speeches. I always forget.

"I think if you write it down, you're expecting to win, and I'm not expecting to win," he continued. "I think if I win, it will be a surprise. I probably will have one of those memorable speeches where I'm just like, 'Cheers!'" 

Fun. are among the most nominated stars at the event with a total of six nods and will also be performing on the night.

Other acts taking to the stage include Justin Bieber, Alicia Keys and a special collaboration between Rihanna, Sting and Bruno Mars.

The Grammy Awards 2013 take place live from the Staples Center in Los Angeles on 10th February.
