Despite the cheating rumors surround her man Scott Disick, Kourtney Kardashian was all smiles as she was spotted leaving the Barnes & Nobles store in New York City yesterday after her book signing for her latest venture Dollhouse, co-authored with sister Khloe.

Those rumors? That Kourtney’s longtime beau and father of her child, Scott, had been cheating on her with The Hills and Dancing With the Stars’ Kristin Cavallari before she was pregnant with their son Mason. Kristin has flat out denied the allegations.

Apparently Scott Disick hasn’t been showing up in support of Robert Kardashian on Dancing With the Stars. I don’t know this, of course, because I can’t make it 5 minutes through that show. Anyway, apparently Scott has been BANNED from the set of the ABC hit because Scott’s a cheater. Gasp!

According to Life & Style, Scott hooked up with Kristin Cavallari, while he was on a break from Kourtney.

With Rob Kardashian on Dancing With the Stars, the whole Kardashian clan came out each week to show its support. Well, almost the entire clan. Absent until the Oct. 31 show was Scott Disick, the father of Kourtney Kardashian’s son, Mason! Now insiders tell Life & Style that Kourtney had banned her boyfriend from the tapings — and with good reason!

In the new issue, on newsstands now, sources reveal to Life & Style that Scott had an affair with Kristin Cavallari, a DWTS contestant until being eliminated in early October and newly single at the time, just before Kourtney became pregnant with her and Scott’s child.

“While Kourtney and Scott were on a break, Scott hooked up with Kristin,” a friend reveals to Life & Style.

So when both Rob and Kristin were confirmed as contestants on DWTS, “Scott and Kourtney argued about Kristin,” a friend confirms. “Kourtney can’t stand her now and didn’t want Scott at show tapings.”

A Kardashian pal confirms that “Scott and Kristin hooked up in Las Vegas during a time [February 2009] that he was on a break from Kourtney.” The Kardashian pal adds that Kristin, Kourtney and Scott were best friends with Kristin during her Laguna Beach days and even after Kristin stopped dating Kourtney’s stepbrother Brody Jenner. Hanging out at Brother Jimmy’s in NYC or dancing at the Fontainebleau Hotel in Miami, the three reality stars were close until Kourtney first caught Scott and Kristin on a date at Apple Lounge in LA on March 11, 2009.

She and Kristin have been enemies ever since. “Kourtney was furious,” the Kardashian pal tells Life & Style. “She and her sisters have called Kristin ‘the whore bag’ ever since.”

But that wasn’t the only rendezvous Scott and Kristin had. “Actually, Scott and Kristin were hooking up on and off for a year, maybe even two,” a second Kardashian friend reveals to Life & Style. “When Kourt and Scott would fight, he’d party with Kristin and hook up.”

Things have gotten so bad between Scott and Kourtney lately that an insider tells Life & Style that Scott moved out of their hotel suite and into his own room at the Gansevoort Park Avenue in NYC while the two were in town filming Kourtney & Kim Take New York. “I’m seeing Scott slip back into his old patterns,” Kourtney says in the Nov. 27 premiere of Kourtney & Kim Take New York.

First Kim and Kris – and now THIS!? Is nothing sacred anymore?

As the “Saturday Night Live” sketch version of Kris Jenner put it, “I know a lot of people think Kim got married just to earn over $17 million from the wedding, but that’s not true. She also got married for attention.”

Here it is! Just five days after E! reality star Kim Kardashian announced she was ending her marriage of 72 days, “SNL” went at her with every ounce of will it had in its writers room.

This morning everyone is talking about the sketch. Several people have lashed out on Twitter, calling the skit “too harsh”. Others think it was pretty funny.

Khloe Kardashian says she can laugh at it: “u have 2learn2 laugh at urself life is 2short” she wrote in a tweet. When asked if she was offended, she wrote “Its SNL… They r supposed 2make fun Its not who we are&I know that.” Kourtney also appeared to have enjoyed it. She simply wrote: “I peed!”

What do you think of the short? It was HILARIOUS. Everything – down to Bruce Jenner’s face was priceless!

According to Kris Humphries, he was completely blindsided by the fact that his wife of 72-days filed for divorce this morning! In a statement to TMZ, Kris said, ”I’m committed to this marriage and everything this covenant represents.”

Kris adds, “I love my wife and am devastated to learn she filed for divorce … I’m willingto do whatever it takes to make it work.”

You gotta feel for the guy!

Khloe and Kourtney, however, were not blindsided! They’ve released statements of their own as well.

Kourtney writes:

“Our sister is going through a difficult time but we”re a close family and are sticking together like always. Kim, we love you. We appreciate everyone’s kindness and support.”

Khloe writes:

“I just want to thank all of our amazing fans for your unconditional love and support. My sister is going through a very difficult time and your kindness right now means the world to all of us. Kim, we love you more than anything.”

Here’s a little recap:

Kim Kardashian released a statement to E! News regarding her divorce.

“After careful consideration, I have decided to end my marriage,” she said. “I hope everyone understands this was not an easy decision. I had hoped this marriage was forever, but sometimes things don’t work out as planned. We remain friends and wish each other the best.”

Khloe, Kim and Kourtney Kardashian are seen here on the ‘Jimmy Kimmel Live!’ stage in L.A. as part of a special ‘Extreme Makeover: Home Edition’ on Oct. 30.

The Kardashian sisters were taking a stand against bullying. They were joined by Demi Lovato, who gave a special performance.

After taping finished, Kim tweeted: “The Walker family touched my heart today! Their 11yr old son hung himself after being bullied at school! THIS HAS TO STOP! #EndBullyingNow!”

PS: How dreadful is Khloe’s outfit!? Yikes!

These pictures were taken last night, pre-split announcement!
