'I don't know them!' Mariah Carey takes a swipe at Jennifer Lopez and Nicki Minaj AGAIN as she rolls her eyes when asked about her rival divas

She has regularly thrown shade at both of them in the past.

And Mariah Carey wasn't easing up on Jennifer Lopez and Nicki Minaj when she appeared on US TV show Watch What Happens Live on Tuesday night.

The Hero hitmaker, 46, was asked about her rivals by host Andy Cohen, after the notorious video when she dismissed J.Lo by saying: 'I don't know her'.

Eye roll: Mariah Carey wasn't easing up on Jennifer Lopez and Nicki Minaj when she appeared on US TV show Watch What Happens Live on Tuesday night

Dismissed: The Hero hitmaker, 47, was asked about her rivals by host Andy Cohen, after the notorious video when she dismissed J.Lo by saying: 'I don't know her'

She reiterated her claims when quizzed about the Jenny from The Block star, and gave a dismissive eye roll when her former American Idol nemesis Minaj was brought into the conversation.

After being asked if the pair are 'cool', a riled Mariah replied: 'I don’t know her. What am I supposed to say? I’m not going to put on a thing like "Oh we're all Hollywood and let’s all pretend we’re best friends" because we're in that land.

"It’s no offence to anybody. The question was about Beyonce and I said she was super talented, she's a friend of mine, she's always been sweet to me, and then they asked me another question and I don't know how I said it but I said, "I don't know her.'"

The superstar went even harder on Nicki, who she famously clashed with during their run on the US talent show in 2013.

When Cohen asked her to say three nice things about the rapper, she stared blankly at the camera and continued to sip her drink.

The interview didn't get off to the best start as the singer arrived late for the live show. 

Cohen was left hanging alone for a few excruciating moments while he waited for the singer to arrive.

The 47-year-old host was also sitting in the chair usually allocated for his guests, rather than his usual seat, because the tardy powerhouse insisted on displaying her 'good side'.

'I love live TV… because not only am I sitting in the wrong seat, I'm not sure why, I'm sure she'll tell me when she gets here… but Mariah Carey is not here,' grumbled Cohen as he waited for Mariah's arrival on live air. 

Empty chair: Andy was left hanging on Watch What Happens Live on Tuesday when guest Mariah Carey showed up late and he was forced to start the show with an empty chair

She made it: Mariah was a few minutes late to the live Bravo chat show - and offered no apology

Kind of worried: Andy took to Snapchat just minutes before the show with Mariah nowhere in sight

'She's not here… I think she's coming up in the elevator… are we going to bring her out? No?' bumbled Cohen as he was forced to stall for another few moments.

'We have champagne ready for her, we have a little fan for her,' sighed the Real Housewives executive producer.

'She is the only person who could ever get me to switch chairs for a reason that has not even been explained to me,' complained Cohen comically. 

When Mariah finally swooshed in she gave no apology.

'Sometimes I like this side better and sometimes I like that side better…it depends on the lighting,' she explained as she gently touched her hair and flipped her head.

As she settled into the interview the Vision of Love star was her usual imperious self, acting exuberantly sarcastic about missing the American Idol finale. 

Switched chairs: The Bravo host was stoked when Mariah finally arrived and didn't mind changing chairs

Grand entrance: Mariah wore a revealing black dress that showed her ample cleavage

Air kiss: The pop superstar gave Andy an air kiss as they greeted each other

'I was heartbroken, I was in misery, no really, I was at home crying,' she scoffed.

When asked to say 'three nice things' about Nicki Minaj she failed to list even one.

'Can you?' she asked Andy while playing Plead The Fifth.

Good question: Andy asked Mariah if she could say 'three nice things' about Nicki Minaj

Andy admired Mariah's 35-carat diamong engagement ring and revealed the poll question asked whether her ring was 'too big' or 'just right'. 

'Anyone who says "too big" is a hater,' the star declared.

Mariah and Australian billionaire James Packer in January announced they were engaged. 

Major rock: Mariah at Andy's insistence showed off her 35-carat engagement ring

Talking of her fiancé's wealth, and the possibility of a prenuptial agreement, she said: 'Everybody's valuable'.

While admitting to never driving a car for herself due to an expired license, Mariah said she is capable of getting ready without her glam squad.

The five-time Grammy-winning singer also claimed to cook 'all the time' for her five-year-old twins – Moroccan 'Rocky' Scott and Monroe Cannon.

Good side: Andy welcomed Mariah to the show and let her sit in her preferred chair showing her 'good side'

'But Rocky doesn't care about food so I have to give him like protein shakes and mix it with a lot of chocolate,' she admitted.

Her favorite TV shows she said are Scandal, Empire and the recently concluded Boardwalk Empire.

When asked if she might make a cameo on Empire she predicted that director Lee Daniels might not meet her wardrobe standards.

Drink to that: The pop superstar opted for bourbon whiskey and ginger ale over champagne

'Leave it to Lee and he'll have me in a wig that he took out of the garbage can,' she smiled.

And when asked to judge a drag queen contest Mariah picked a lookalike inspired by her Heartbreaker collaboration with Jay-Z. 'I love Heartbreaker so much,' she cooed.

The Las Vegas residency holder said she had 'never talked about' a collaboration with Beyonce, which has been rumoured for some time.
