Taylor Swift is no stranger to putting on an amazing show, and with her glow-up in performing, she has been able to take things to another level on stage, and has made a fortune doing so.

We love a supporting artist, and years back, Billie Eilish and her brother was caught being supportive and singing along to “Blank Space” by Taylor Swift. It’s a beautiful moment to see, and it’s one that has some history attached to it.

Billie Eilish Was Caught Singing Along To Taylor Swift’s Performance Of “Blank Space”

Artists love showing out for other artists, and while Taylor Swift was on stage rocking her performance of “Blank Space.”

The shots largely focus on Swift and her dancers, but the cameras panned through the crowd, catching Billie Eilish and Finnaes jamming out to the song.

“Billie and finneas vibing,” one user pointed out in the comments.

The performance took place at the 2019 American Music Awards. During that evening, Swift took home the Artist of the Decade Award, and she performed a brilliant medley of songs for her global audience.

“I guess what I’m trying to say is that all anyone in this room wants is to create something that will last, whatever it is in life, and the fact that this is an award that celebrates a decade of hard work and of art and of fun and memories—all that matters to me is the memories that I’ve had with you the fans over the years. you guys we’ve had fun, incredible, exhilarating times together, and may it continue,” Swift said, per Pitchfork.

Interestingly, Eilish being caught enjoying the show also serves as a reminder that she was a Swift fan growing up.

When speaking with iHeart, Billie touched on many topics, eventually revealing that her favorite song growing up was by none other than Taylor Swift.

“I used to love this song when I was, like, four — no, probably older than that. Probably, like, six. It’s crazy. It’s very country. When I listen to it now, I’m like, ‘Wow, I totally didn’t realize how country this was.’ But I loved this song back then because I thought it was so bada–. I thought it was so cool and mean. I just loved it,” she said.

She then added that she had no idea that it was a Taylor Swift song until she was an adult.

“I actually didn’t know it was Taylor Swift until this year. I didn’t understand at all what a ‘picture to burn’ meant. The only word ‘burn’ that I knew, that I thought that she meant, was, like, when you burn a CD,” she said.

Turns out, the feelings of admiration flow both ways.

Taylor Swift Has Given Praise To Billie Eilish In The PastInstar

Previously, Taylor Swift has given flowers to many women in the music business, including Billie Eilish.

“Let me just say that the definition of the toxic male privilege in our industry is people saying, ‘But he’s always been nice to me,’ when I’m raising valid concerns about artists and their rights to own their music. And of course he’s nice to you. If you’re in this room, you have something he needs,” Swift said.

“The fact is that private equity is what enabled this man to think, according to his own social media posts, that he could ‘buy me,'” Swift said. “But I’m obviously not going willingly,” she said.

She went on to add, “Yet the most amazing thing to discover was that it would be the women in this industry who would have my back, and show me the most vocal support at one of the most difficult times. And I will never, ever forget it. Like, ever.”

Billie Eilish, Lizzo, Dua Lipa, Halsey, Normani, H.E.R., and a few others were all named by Swift, which was a major moment for the industry.

This moment took place at that Billboard Women in Music Awards, and it was held right before Swift turned 30. The speech itself was empowering, and Swift used her platform to both raise awareness, and to put other artists on.

A candid shot of Billie Eilish singing along to Taylor Swift’s performance is a nice reminder that all musicians are fans, too. Before they were rocking the stage, they were rocking in their bedrooms to artists they had no clue would be their peers one day.
