Kim Kardashian awkwardly interrupted her big sister Kourtney on the People's Choice Awards red carpet in Los Angeles this Sunday.

The duo, their sister Khloe and mother Kris Jenner were chatting with Giuliana Rancic of E! News who asked what designers they were wearing.

'I didn't plan this - Naeem Khan? Is that how you say it?' Kourtney, 40, began, before Kim, 39, leaned in front of the microphone and interrupted.

Uncomfortable: Kim Kardashian awkwardly interrupted her big sister Kourtney on the People's Choice Awards red carpet in Los Angeles this Sunday

'All that matters is that we're wearing KKW Diamonds! That's all that - we're all wearing that,' said Kim, conveniently plugging her own fragrance line.

'I was saving you since you didn't know who you were wearing,' Kim told Kourtney with a condescending smile.

'No, it's Naeem Khan, I just didn't know how to pronounce it,' said a quietly spoken Kourtney, to which Kim offered a slightly skeptical-sounding: 'Oh.'

As the interview wore on, Kourtney wound up disappearing from the frame entirely while Kim, Khloe and Kris spoke with Giuliana.

Kim notoriously accused Kourtney of being workshy on a 2018 episode of their reality series Keeping Up With The Kardashians.

She dismissed Kourtney as 'the least exciting to look at' in the family, saying: 'She doesn't do s***. She doesn't know what it's like to actually have f***ing work to do.'

They have frequently clashed on the current season as well - although it was filmed months ago and Kim tweeted in September: 'Fighting is over don't worry'.

This latest season alone, Kim has accused Kourtney of stealing her dress sense and has called her a 'f***ing fake humanitarian hoe.'

Always selling: 'All that matters is that we're wearing KKW Diamonds! That's all that - we're all wearing that,' said Kim, conveniently plugging her own fragrance line

What a boon: 'I was saving you since you didn't know who you were wearing,' Kim told Kourtney with a condescending smile

Sure: 'No, it's Naeem Khan, I just didn't know how to pronounce it,' said Kourtney, to which Kim offered a slightly skeptical-sounding: 'Oh'

As Kim recounted later to Kris, she told Kourtney: 'I actually do s*** for the world, and you f***ing fake it all day long and act like: "Oh, there's people dying, Kim!" And what the f*** are you doing about it? So shut the f*** up.'

Kourtney famously said: 'Kim, there's people that are dying,' on a 2011 episode as her younger sister wept over a lost diamond earring.

Keeping Up With The Kardashians won best reality show Sunday night at the People's Choice Awards, which were held at the Barker Hangar in Santa Monica.
