Kanye was "freaking out" after the first tape emerged last week, featuring him and girl who looks like his current girlfriend Kim Kardashian, and this second recording is double in length.

TMZ.com reported: "Both tapes are impressively long - the first is roughly 20 minutes and the second is more than 40.

"And we're talking constant action. Seriously, the guy takes no breaks. It's incredible."

Both tapes were made before he started dating 31-year-old Kim, who was catapulted to fame after becoming the unwitting star of her own sex tape in 2007 when her ex-boyfriend Ray J released the recording.

The 'Stronger' hitmaker has called in his lawyers to stop any footage of the tapes from being released, and it is believed the material has been stolen from his personal computer.

In regards to the first tape, his lawyer Lisa Buckley released a statement conforming it is Kanye in the video and warning against any party distributing images or clips from it.

She said: "Your posting, advertising, marketing, displaying and otherwise disseminating the stolen screen shot and/or other materials on the tape constitute actionable violations of Mr West's rights of privacy and publicity."
