There was reason why Kim Kardashian started her struggle to lose the baby weight soon after North West was born. The socialite is appearing in a "really sexy" music video for a new single "Bound 2" from her fiancé Kanye West's latest album "Yeezus," U.S. Weekly reports.

A clip of the Kim Kardashian music video will be debuted exclusively on "The Ellen DeGeneres Show" on Tuesday night. And we are sure the curvaceous Kim is more than ready to feature as a model on the music video. The new mommy is flaunting her newly achieved figure to her fans. Some time back, the mother with a sexy bum posted a selfie on Instagram where she is seen in a swim suit that barely covers her pert behind. The picture generated lots of views from Kim's fans and even had an eager Kanye writing "I am coming home NOW" on Twitter.

The 33-year-old socialite is also displaying her sexy cleavage on many occasions be it the fashion shows or outings with would be hubby Kanye West. The sexy momma is back to where she started her social life after taking a brief hiatus before and after baby Nori's birth.

Here are some details about the music video, which will be directed by fashion photographer Nick Knight. On her Web site, the host Ellen hinted the fans about the presence of Kim in the upcoming music video of Kanye saying it "may or may not feature his stunning and curvalicious fiancée." Kanye West's friendship with Ellen goes back to 2008 when she also premiered the rapper's "Love Lockdown" video on her show.

"Kim looks beyond gorgeous. It's very artsy, very beautiful. The imagery is very colorful and light. Nothing about it feels pop or urban. She looks incredible," a source tells the website U.S. weekly about the video.

It is unclear what part Kim Kardashian will play in the music video of "Bound 2" or what kind of dress will she be wearing. Kanye has a history of making hot music videos like his 2005 hit "Gold Digger." Let's see what the rapper has in store for his future wife.
