Billie Eilish was spotted sitting in an economy seat on a commercial flight.

An excited fan with the username @williambosanova took to TikTok and shared a shot of the 21-year-old sitting rows away.

The pop music sensation – who recently flaunted diamond grills – was highly visible in the clip wearing a gray beanie with blue stars outlined in white all over.

The singer confirmed that it was in fact Billie who the eagle-eyed passenger was peeking at and later appeared on her Instagram page in the look.

Using the Stories feature, the Bad Guy singer shared a selfie she took in her chair with the sunlight shining on her face.

The plane’s overhead cabins were visible in the background, and she linked the Future song I Serve The Base over the image.

Eilish went makeup-free and her blue eyes sparkled as the sunlight hit them.

The fan who posted the sighting on social media has gone viral and the clip has been viewed nearly 900,000 times.

The post caption read, “Pov: You’re on a plane with Billie (still can’t believe it just happened).”

And the entire recording had a similar caption: “POV: You see Billie Eilish for free.”

There was no mention of which airport the superstar boarded the plane at, or where the flight was going.

Last week, the Gen-Z favorite took the stage at Sziget Festival 2023 in Budapest, Hungary.

She showed off her fun fashion sense as she performed in a black sweater with white and red accents, red athletic shorts and black tights.

One of the Grammy winner’s recent Instagram posts showed her with new diamond grills adorning her teeth.

The photos sparked a debate among her 110 million followers, as some thought the accessory was cool, while others disagreed.

Social media users wasted no time in heading to the comment section to offer up their contrasting shots.

One fan defended the grills, writing, “Obviously hip-hop influenced. She’s always done the big clothes, but let’s not deviate from the fact that the jerseys, Jordans, and grills are regular hip-hop groups.”
