Kourtney Kardashian Obsessed with Justin Bieber’s Body?

Despite the fact that they haven't officially confirmed that they are dating, Kourtney Kardashian is said to be letting her relationship with Justin Bieber become on obsession. According to the latest gossip news updates, the Keeping Up with the Kardashians reality TV star is so impressed with The Biebs' hard body that she is doing everything she can to get her 36-year-old physique into tip-top shape. Word has it that while her sister Khloe is getting all the attention for the recent weight she has lost, Kourtney is as skinny as she has ever been.

While they have yet to make anything official, Justin Bieber and Kourtney Kardashian are said to have been seeing each other for quite some time.

One eyewitness source in the latest December 28, issue of In Touch claims to have seen Bieber and Kourtney publicly making out at The Nice Guy in West Hollywood a couple weeks ago:

"He was already there when Kourtney arrived and sat next to him, then they started kissing.

"Not everyone could see them, but they were all over each other, definitely hooking up.

"There was so much chemistry even though there was a huge age difference."

Rumor has it that the age difference is starting to take its toll on Kourtney in more ways than one, as the mother of three reportedly works night and day at keeping herself in the sort of shape as Bieber's much younger love interests.

The secret insider that Hollywood Life spoke to insists that although Kourtney looks great, the constant working out is starting to take up an unhealthy amount of the reality star's attention:

"Kourtney is getting more and more obsessed with her looks since hooking up with Justin.

"He's only 21 and has perfect skin and a flawless fat-free body.

"Kourtney is working out like never before, making sure she's super skinny."
