Kourtney Kardashian: 'Kim has great voice'

Kourtney Kardashian has said that sister Kim has a "great voice".

The reality stars' new series Kourtney & Kim Take New York! will feature an episode where Kim records a track with The-Dream, with proceeds from the song being donated to a cancer charity.

"I was in the studio and Kim actually has a great voice," said Kourtney on Friday's episode of The Wendy Williams Show.

"I was doing it for fun," added Kim. "The-Dream, Ciara… they all talked me into doing it. I was not into this. I was like, ‘You know what, everyone tries this. I have too much going on, I don’t want to do this…’ We decided to do it because it's something I was so nervous about.”

The 30-year-old, who shot the music video at Tao Las Vegas, went on to say that she has only recorded one track and has no plans to release an album.

The new series, which premiered last night, follows Kim and Kourtney as they attempt to launch a new branch of their Dash clothing store in Manhattan. Khloe previously explained that she was sitting out the series in order to stay with husband Lamar Odom in California.
