Charli XCX made a stylish entrance on day one of Coachella on Friday, turning heads as excitement swirled among fans who believe Billie Eilish may make a surprise appearance during her set.  

The singer, 32, whose real name is Charlotte Emma Aitchison, looked incredible as she showcased her legs in a white vintage Lou Reed T-shirt paired with a floaty satin mini skirt featuring delicate pearl detailing. 

The 365 hitmaker accessorised her effortlessly cool look with a black quilted Chanel crossbody bag and trendy black sunglᴀsses.

To complete her festival-ready ensemble, Charli wore pale pink ballet flats and let her wavy dark hair cascade freely over her shoulders. 

In high spirits, she arrived at the star-studded event alongside two friends, exuding confidence ahead of her weekend performance. 

While Lady Gaga, Travis Scott, Green Day, and Post Malone are set to headline this year’s festival, Charli is scheduled to hit the main stage on Saturday, April 12, and again on Saturday, April 19.

Speculation around a surprise Billie Eilish cameo began brewing on Friday after the 23-year-old shared a cryptic lime green Instagram Story – fuelling theories among fans that she’ll join Charli on stage. 

Her fanbase went wild in August when 32-year-old Charli enlisted her for the remix of her cheeky song Guess.

Now, listeners are convinced the two performers will bring the collaboration to life in the desert this weekend.

One person wrote on X, formerly known as Twitter, ‘I better see her on that stage for the guess remix please GOD.’

Someone else added, ‘Billie cosigning BRAT green before Coachella? Oh yeah, something’s definitely brewing. A Billie x Charli moment would shake the desert.’

Another fan said, ‘omg incoming Billie Coachella serve.’

Social media user @SirTopiano weighed in, ‘Billie already speaking loud without saying a word.’

One year ago Billie made festivalgoers ecstatic when she emerged to perform two songs with headliner Lana Del Rey.

Meanwhile, actress Nina Dobrev looked effortlessly cool in an oversized black T-shirt paired with knee-high boots as she arrived at the festival alongside her fiancé, Shaun White 

American actor Dylan Minnette and his stunning girlfriend Isabella Elei put on a sweet display as they strolled hand-in-hand into the festival

Meanwhile, rapper Travis Scott, who’s set to perform, kept a low profile and hid his face as he made his way inside 

The duo performed Eilish’s 2016 track Ocean Eyes before delivering a rendition of Del Rey’s 2012 ballad Video Games.

While on stage, the Bad Guy hitmaker gushed about Del Rey’s impact on not just her, but also her legion of non-famous diehard fans.

‘This is the reason for half of you b**ches’ existence…including mine!’ Billie shouted to the audience. ‘Lana Del Rey, you guys, come on!’

Billie and Charli’s Guess remix was accompanied by a flirty and fun music video, in which they incorporated a ton of colourful underwear.

It comes as Billie’s fans began speculating on X that she will pop up at the music extravaganza shortly after the singer posted a lime green Instagram Story on Friday

And after the song’s release, fans agreed the ‘iconic’ tune was ‘life changing’ as they declared it was history being made.

The Coachella 2025 speculation comes two weeks after Billie fuelled romance rumours when she was spotted stepping out in New York City with 30-year-old actor Nat Wolff.

However, a source with inside information has told DailyMail.com, ‘Billie and Nat are just friends.’

It was added: ‘They’re more like siblings than anything else and there is no romance between them. Billie is much more interested in women right now.’
