A source has claimed the Keeping Up With The Kardashians star has been learning piano and working on tracks in the recording studio with her husband Kanye West.
The insider told The Sun: "Kim is excited about the collaboration… Kanye plans to release the song just after Kim has their second child."
Back in February, the pregnant star had told Twitter followers she was learning the piano, but had said it was so she could surprise Kanye by playing one of his songs.
She had tweeted: "Just finished my piano lesson in time to watch the Oscar's red carpet!!! I'm going to surprise Kanye by learning one of his songs! He's hardly on social media so he won't know I'm tweeting this lol."
Kim made her first foray into the music world back in 2011, with the song 'Jam', featuring background vocals by The-Dream. The music video featured a special appearance by Kanye, who was just a friend at that stage.
Proceeds from the track went to St Jude Children's Research Hospital.
