After calling up some of her most famous friends, Billie Eilish might have a prank war on her hands.

The Grammy Award winner, 22, had some fun with her contacts as she prank called Margot Robbie, Tyler the Creator and Dakota Johnson in a hilarious video for Elle.

She started by asking Robbie, 34, if she could use the Barbie star’s house to film a music video after another location fell through.

I ordinarily would say f*** yeah, but uh, we are packing up our house tomorrow,’ Robbie told Eilish before trying to help her find another option.

Eilish noted, ‘There’s going to be probably about like 200 extras I know it’s kind of a lot, but like yeah, it’ll be like a lot of people. Lotta space.’

After the Hit Me Hard and Soft artist admitted the call was a prank, Robbie was a good sport.

‘Prank me anytime. And also if you ever have a real request like that feel free to call me,’ she said.

Calling up Tyler, 33, Eilish made up a story that she was on a date and pooped her pants. ‘Fire. Honestly, Fire. You deserve it,’ he responded.

In her call with Johnson, 34, Eilish said she was ‘being offered a role in a movie where they want me to play like, a baby.’

‘Like I’m so serious they want me to play a baby but they’re offering me like, $500 million dollars.

‘But they want me to literally play like a baby,’ added Eilish. ‘I’m like in a diaper, and I’m like, yeah, a baby.’

After admitting the movie will be ‘probably really bad,’ Eilish went on to ask for a dialect coach recommendation before admitting it was a prank.

‘I was gonna ask you if it was a prank!’ said Johnson. ‘Can you imagine if my next thing to say was, “Don’t you have enough money already?”‘

Johnson added menacingly, ‘Just watch out for me. Here I come. Just watch your back.’

‘Oh my God I could throw up right now … my body is a temperature that it’s never been,’ she prefaced

‘Justin, I have something to tell you,’ said Eilish. ‘Dude, I can’t do this s*** anymore like, I’m gonna quit music and I’m not doing this anymore.’

Before she let him in on the joke, Lubliner appeared concerned with her wellbeing. ‘You know, forget the business for a second, like what’s, can you tell me what’s going on?’ he asked.

‘I’m a human at the end of the day,’ added Lubliner. ‘So put business and work relationship aside like I want to make sure you’re okay.’
