William Orbit is a Britney Spears ''superfan''.
The producer worked with the pop star on the track 'Alien' for her forthcoming new album, 'Britney Jean', and is now such a big fan he's planning to see her perform at her residency in Las Vegas, which starts in December.
He told NME magazine: ''I've done one song for the new album, called 'Alien', which is really good. I'll be in Vegas, seeing the show. I've become a huge fan of hers, actually. I always liked her, but when I started to dig into her repertoire - and there's masses of it - I became a superfan, really. You'll find me in the audience singing along.''
While William, 56, is a huge fan of Britney, he has recently fallen out with indie band Blur - led by Damon Albarn - after he worked with them last year but the sessions came to nothing.
He said: ''Oh don't start me on Blur. Put it this way, I'm not going to work with them again - Damon was really awful. That's all I'll say. Let's put it this way, I wouldn't care to go back. I wouldn't be hurrying back to do that album. I didn't get paid! But, you know, I'm not the first.''
William previously had a good relationship with Blur, producing songs on their albums '13' and 'Think Tank'. He has previously also been behind huge hits by Madonna and All Saints.
