The 23-year-old singer, famous for songs such as Rolling In The Deep and Someone Like You, will be heard on a new record that she is doing with the Pass Out star.
He said to UK newspaper Daily Mirror: 'We're working on something together. It's going to be something amazing. You'll all hear about it very soon.'
The rapper added that he misses a lot of things from Britain when he's out of the UK.
He said: 'I miss tea when I'm away, so I'm trying to drink as much of it as possible while I'm back. I overdosed on English Breakfast - I've rinsed that. So I'm trying other varieties now.'
