Billie Eilish and Alicia Keys are taking their mutual love to a whole other level.

On December 9, when Alicia was filling in for James Corden on The Late Late Show, the two singers performed a stripped-down rendition of Billie’s breakthrough hit “ocean eyes.”

“We need some dramatic lighting,” Alicia said before unveiling her piano and kicking off the song. The duet version featured Alicia on the piano (sorry, Finneas!) and mixed both singers’ honeyed vocals to perfection, making it the collab we never knew we needed.

Back in August, Alicia posted a piano cover of the song to her IGTV. “Billie Eilish giving me all the feels … Keep shining mama, writing that truth,” she wrote back then. “I’m a super, super fan of yours — I love how you write, I love your music,” Alicia told Billie on the show.

And it turns out, the love was very much reciprocal. “I have adored you my whole life,” Billie told Alicia before sharing a throwback clip of her 12-year-old self covering Alicia’s 2001 hit “Fallin’” — also at her piano. To further commemorate the occasion, Billie also posted a few of the snippets from their respective covers on her Instagram, writing, “CRAAAAZY full circle moment… love you so much @aliciakeys thank you for everything you are, can’t believe any of this happened. you in my heart forevaaaaa.”

“You got one for me and I got one for you. We’re going to do the next one soon,” Alicia told Billie after watching the adorable clip. And you can bet we’ll take her up on that one.

Her When We All Fall Asleep track gets a self-directed visual

Billie Eilish has shared a music video for her When We All Fall Asleep, Where Do We Go? track “xanny.” Check out the self-directed visual below.

When We All Fall Asleep arrived earlier this year, marking Eilish’s debut studio album. So far she’s shared music videos for her hit single “bad guy” and “all the good girls go to hell.”

Since the release of When We All Fall Asleep, Eilish has performed at Coachella and made her debut as musical guest on Saturday Night Live. She’s also shared a remix of “bad guy” featuring Justin Bieber. Eilish heads out on a world tour in March 2020.

Billie Eilish isn’t here for age or gender restrictions on clothing.

Speaking to DJ Zane Lowe before her and Finneas’s performance at the inaugural Apple Music Awards on December 4, the “Bad Guy” singer opened up about her frustrations with traditionally gendered fashion, admitting she used to wear “boys’” clothes growing up to find pieces that suited her liking.

“I grew up always getting boys’ shoes and boys’ clothes,” Billie told the audience at Apple Park’s Steve Jobs Theater. “I [asked,] ‘Do you have these in a women’s size?’ and the answer would always be no.”

This, Billie revealed, was one of the driving forces for launching her very own kids’ clothing line, which she unveiled on Instagram back in November. “It’s the same thing [for kids] when you see a shirt for a grown-up,” she continued. “I talked to a lot of people I know that have kids and they are always talking about how there are no cool kids’ clothes.”

“I don’t want anything to be limited,” the singer pointed out about her apparel offering. “I didn’t want anyone to feel like they couldn’t get the clothes that they wanted.” And clearly people feel the same way. Billie’s kids’ clothing line was a hit, with the neon green “Billie” hoodie selling out mere hours after its launch (it’s currently being restocked and has a six-week preorder waiting time).

This isn’t the first time Billie has spoken about the limitations of gendered clothing. During her episode of Complex’s Sneaker Shopping earlier this year, the singer admitted she favors “big” and bulky shoes, meaning she’s often forced to gravitate toward men’s shoes due to the limited women’s sizing. “I just like the idea of being able to go into a store and being able to say, ‘Do you have this in my size?’ and it’s a yes. I don’t want to hear no,” Billie admitted back then. Same, Billie, same.

Jimmy Kimmel Live! must have an excellent child-casting service. Whenever they need to have kids react to Star Wars toys or have their Halloween candy taken away, they find the cutest little nuggets. And when they need a child to talk to Billie Eilish about how Pennywise the Dancing Clown is drinking a grandmother on her head, well, they can find that kid, too. Billie Eilish asked kids where they go when they sleep, and their answers ranged from the horrifying to the adorable. If Tiffany Haddish ever gets tired of hosting everything, she can give Kids Say the Darndest Things to Eilish. It’ll be in good hands.
