Adele's Rolling In The Deep topped the US singles chart
The quirky remix is the brainchild of Daft Beatles - and the result is surprisingly catchy.
While Adele, 23, is a record-breaking solo artist who's conquered America, Girls Aloud star Nicola has only recently gone it alone.
But she's confident she can make her song a success.
'It's a fun record,' Nicola, 25, tells The Sun.
'It was important my first single was different to anything else around.
'I love that it's a song everyone can sing and dance along to.'
