Happy twerk-day!

TV personality and rapper Bhad Bhabie — born Danielle Bregoli — was spotted twerking Sunday in a bright pink bikini at her 20th birthday party at the rapper’s home in Florida, reported TMZ.

The 20-year-old singer spent her big day with her mom, Barbara, and a small group of both her and her mom’s friends, according to the outlet.

Things at the party took a turn when Bhabie began shaking her tail feathers and twerking up a storm.

At one point, the entertainer — who vaulted to questionable fame for uttering the phrase “cash me outside” in 2016 — begins to straddle a chair occupied by her mother.

“She didn’t learn this from me because I don’t know how to do it,” declared Barbara, speaking to the camera about her impromptu lap dance.

The Post has reached out to Bhabie for comment.

Bhabie became an internet sensation after she and her mom appeared on an episode of “Dr. Phil”, where the singer started dropping her catchphrase: “Cash me outside — how ’bout dat?”

The rapper’s interview has racked up some 14 million views on YouTube.

Seven years after her national TV debut, Bhabie has dropped three tracks that have cracked Billboard’s Hot 100 chart, the most recent in 2018.

Bhabie recently purchased a seven-bedroom, seven-bathroom mansion in Boca Raton, Florida, for a whopping $6.1 million deal — all in cash.

The 9,200-square-foot home pad is the second home that Bhabie has owned: The first is a five-bedroom, seven-bathroom estate in the same neighborhood that was valued at nearly $4 million when she put it on the market last year.

People can “cash her” on OnlyFans, where the sensation reportedly racked up nearly $1 million dollars in the first six hours of her joining the app.

Last year, Bhabie has also expressed the wish that her fans would move on from her infamous interview with Dr. Phil.

“[People think] I’m so in love with being the girl who got famous for being on ‘Dr. Phil’ and saying some crazy s–t. That’s not how I feel,” declared Bhabie. “Call me the youngest female of the decade to go platinum … Call me some s–t like that! Call me the girl who got a million-dollar makeup deal! The girl who made over 50 million dollars on OnlyFans!”
