Lainey Wilson is celebrating National Bell Bottoms Day (April 5) in true Lainey style—with the release of a brand-new party anthem, “Bell Bottoms Up.”

Known for her retro flair and Southern sass, Wilson co-wrote the high-energy track with her band and recorded it at the iconic Abbey Road Studios in London—shouted out right at the start of the song.

The upbeat tune is packed with confidence and Wilson’s signature sound.

With bold lyrics like

“I’m fillin’ up these jeans like I do my cup / Throwback, throw down, bell bottoms up,” it’s all about letting loose and owning your individuality.

“Bell Bottoms Up” isn’t just a song—it’s also the name of Wilson’s Nashville bar, which opened last year in the former FGL House space.

The three-story venue features Cajun-inspired food, multiple stages, and even a rooftop hangout spot with Wilson’s Louisiana roots sprinkled throughout.

The release follows a major moment in Wilson’s career—recent No. 1 hits “Wildflowers and Wild Horses” and “4X4XU.”

She’s also been performing “Bell Bottoms Up” on tour, where it’s already become a fan favorite.

Next up: the U.S. leg of her Whirlwind World Tour, kicking off August 14 with special guests Ernest, Muscadine Bloodline, and more.
