Mark Ronson has admitted he thinks it's "nuts" just how successful his song 'Uptown Funk' now is.
The music producer collaborated with Bruno Mars on the award-winning tun, and admitted he's stunned by the triumphs it's had internationally.
Speaking after winning the Best British Single at last night's BRIT Awards with MasterCard, he explained: "It's just nuts. I didn't even realise we were actually eligible. It's insane.
"This song that started as a jam in Bruno's studio in LA just about a year ago, people have taken it on and love it and it's just nuts."
Mark fought off competition from huge hits including Clean Bandit's tune 'Rather Be', Ed Sheeran's 'Thinking Out Loud' and Sam Smith's 'Stay With Me' amongst others, and he was shocked to even be nominated alongside such artists.
"What's really cool is when I go to New York and I turn on Hot 97, I hear Clean Bandit and I hear Sam Smith and then you change the station and you hear Calvin [Harris] or Ed Sheeran.
"The singles like that - which are massive all around the world, to be recognised in a group with them feels massive."
