Kim Kardashian awkwardly interrupted her sister Kourtney during an interview.

The Kardashian clan were out in full force at the People's Choice Awards red carpet in Los Angeles on Sunday.

The three sisters and their mum Kris Jenner were talking to E! News reporter Giuliana Rancic, 45, who asked what designers they were wearing.

Eldest sister Kourtney, 40, explained: "I didn't plan this - Naeem Khan? Is that how you say it?"

Keen to steal the limelight Kim, who recently turned 39, leaned in front of the microphone and interrupted.

In a cringey display, Kim shouted: "All that matters if that we're wearing KKW Diamonds! That's all that - we're all wearing that." She had no qualms plugging her own perfume line.

"I was saving you since you didn't know who you were wearing," Kim sassily told Kourtney.

"No, it's Naeem Khan, I just didn't know how to pronounce it," a quiet Kourtney replied, as Kim offered an: "Oh."

Now fans have trolled youngest sister Khloe, 35, for not sticking up for Kourtney in the heated moment, saying she didn't deserve the award she had won at the event.

 An angry Kardashian fan tweeted Khloe with: "b***h we ain't voting next year if you just gon stand up there and not say s**t @khloekardashian."

Khloe wrote back: "It's so beyond loud in here. I had no idea I won an individual award until we walked off stage. I feel so badly right now.

"I am so f***ing grateful and appreciative! I can't believe I didn't say anything but I didn't hear that I won until after."
