The X-rated footage features the estranged couple involved in raunchier acts than their first home video which leaked in 2007 and eventually released as a DVD entitled 'Kim Kardashian: Superstar', reported Daily Star.

"It's definitely Kim in the video. And it's even raunchier than her last one. There are all kinds of eye-popping moments," a source said.

The 32-year-old socialite is said to be terrified the latest sex tape will appear online and cause problems in her relationship with 35-year-old rapper Kanye West.

"Kim fears this will damage her relationship with Kanye West," the source added.
