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

A adoring fan with the username @williambossanova took to TikTok and shared a shot of the 21-year-old sitting in the front rows.

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

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

And the entire shot featured a similar caption that read, “POV: Watch Billie Eilish for free.”

There was no record of which airport the superstar boarded the plane at or where the flight was headed.

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

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

Social media users wasted no time in stating their opposing views in the comments section.
