During the first part of "Kim's Fairytale Wedding: A Kardashian Event" which aired on Sunday night, Khloe Kardashian and Kim Kardashian's fiancé Kris Humphries clashed several times as Khloe Kardashian questioned Humphries intentions with her famous sister.

The biggest argument came during Kim Kardashian and Humphries' engagement party held at Khloe Kardashian's home when Humphries walked in on Khloe Kardashian talking about him to a friend. After Khloe Kardashian asked about Humphries' intentions and spoke about her fears onhow fast the couple's relationship was going, Humphries fired back with some criticism of his own.

"What are you trying to say? That I like this world and that's why I'm with Kim," Humphries said. "How dare you question someone else's marriage. Are you sure you're not just using Lamar? He's a Laker, he's got championships. How often are you going to find a tall, successful guy to have kids with?"

Lamar Odom, who plays for the Los Angeles Lakers and is the star of the TV realty show "Khloe & Lamar," married Khloe Kardashian in 2009 after dating for a month.

Humphries later told Kim Kardashian about the incident, which led to her confronting Khloe Kardashian about the situation.

"I don't want this bad energy at my wedding and if all of you are talking [expletive] behind my back there's no reason why any of you should be at my wedding," Kim Kardashian tells her sister during the confrontation.

Khloe Kardashian then asked, "So wait, you don't want me at your wedding?"

"No," Kim Kardashian replied before slamming the door behind her.

In the end, Khloe Kardashian ended up serving as a bridesmaid during Kim Kardashian's wedding to Humphries on August 20.

The second half of "Kim's Fairytale Wedding: A Kardashian Event" is set to air Monday night on E! at 9 p.m. Check out Kim Kardashian's fight with sister Khloe Kardashian below.
