Rihanna confirmed the get together in a tweet on Monday (06Jan14), revealing fans only have to wait a week to hear the track.
She writes, "@shakira - Can't Remember To Forget (feat. @rihanna ) Actually I just found out you'll have it by the 13th! #1week."
News of the collaboration leaked in early December (13), when rapper Pitbull revealed he had initially wanted to recruit the Umbrella hitmaker for his hit song Timber, but she was too busy in the studio with the Latin singer, so he decided to team up with Ke$ha for the track instead.
The Rihanna/Shakira collaboration is expected to feature on the new mum's next album, the follow up to 2010's Sale el Sol.
