Kanye West wants to record a song with his pregnant girlfriend Kim Kardashian so they can play it to their child when the baby is born.

Kanye West is planning to record a duet with his pregnant girlfriend Kim Kardashian.

The ‘Stronger’ hitmaker – who announced on stage last weekend that he and the socialite are expecting their first child together – has booked a recording studio for the end of January and thinks it would be “cool” to make some music they can play to their baby when it is born.

A source told the Daily Star newspaper: “Kanye’s really soppy. He wants Kim to lay down some vocals while she’s carrying his child.

“He thinks it’ll be cool for his son or daughter to listen to the track when they’re older.”

As well as making music together, it has been revealed Kim and Kanye plan to document her pregnancy and their subsequent trials and tribulations as parents in a new reality TV show.

E! Entertainment network president Suzanne Kolb said: “Kim and Kanye are an incredibly dynamic couple, and their baby news is just so exciting. Like so many Kardashian fans, we love it when this close-knit family gets even bigger. We look forward to sharing the joy as they prepare for more diapers, more bottles and without a doubt, more fabulous baby wear.”
