Las Vegas, Nevada – Blame it on her juice!

Lizzo rang in her 33rd birthday with a champagne shower and Sin City sass on Tuesday - while seeming to take a page from Kim Kardashian's fashion book.

The musician danced the night away at Caesar's Palace in Las Vegas in a see-through Jean-Paul Gaultier striped dress.

She posted a video on Tuesday twerking in the piece she called "custom vintage". Fittingly, the outfit was definitely a throwback – to a past look from Kim K!

What could have been a fashion faux pas passed as a double dose of sexy style.

The 40-year-old reality star rocked the same look when she walked the red carpet for the 2018 People’s Choice Awards, pairing the sheer gown with nude underwear.

The birthday girl opted for a white thong.

The dress is from the designer's 1996 collection and again appeared on the runway in 2019, according to Page Six.

"Another year for the history books and anotha look for ya mood board B***H," Lizzo wrote on Instagram on her birthday.

"It should be a sin to look this good in Sin City," she added.

The birthday celebrations started early for the three-time Grammy winner. Lizzo was lounging poolside and "getting spoiled" with Gucci gifts this week, but has kept the identity of her admirer hush hush.

Fans wondered if it could be Chris Evans, with whom she hilariously shared a drunken DM exchange last weekend.

Kim also has been getting back into the mix since filing divorce papers from Kanye West. She hit the nightclub scene in Miami last weekend and has been recently linked to CNN's Van Jones.

Looks like both sexy ladies are similarly stylish, single, and celebrating!
