Bebe Rexha is giving the middle finger to people shaming her for gaining weight.

“I know I’ve gained weight. Humans go through fluctuations,” she captioned the clip Tuesday, which showed her dancing in a sequin orange jumpsuit before flipping off the camera.

“Not gonna lie it does suck and bother me when I read some comments but it comes with the territory,” the singer, 33, went on.

“I’ve been learning not to judge myself and accept myself while also trying to make healthier decisions in my life. What I have learned though is numbers don’t define you, your heart does,” she concluded.

Fans quickly flooded her comments section with words of support.

“MAMA YOU LOOK AMAZING F–K THE HATERS,” one person wrote.

Another added, “I saw you in person this week and couldn’t believe people say anything about your weight! You are absolutely gorgeous and put on an amazing show where you sing, dance and slay at the same time. People throw rocks at things that shine and you are a superstar.”

A third fan chimed in, “Bebe you’re so hot right now. Don’t let the haters get to you.”

In the clip, Rexha danced along to her hit, “I’m Not High, I’m In Love,” while rocking the bedazzled one-piece with corset detailing and bell sleeves.

Her blond hair was styled in voluminous, bouncy curls and she accessorized with matching heart-shaped earrings.

Rexha previously revealed that her weight gain — which she has “always struggled with” — was attributed to a diagnosis of polycystic ovary syndrome (PCOS).

“I literally jumped, like, 30 pounds so quickly, maybe a little bit more. But we gotta just be positive and just show people love,” she said on “The Jennifer Hudson Show” in April.

Her latest post comes one week after a concertgoer was arrested for hurling a cellphone at her face during her New York City show.

The alleged assailant was charged with assault over the incident at The Rooftop at Pier 17, which left her with a black eye.

Video captured by fans showed the singer falling to her knees while crew members rushed to her aid.

The Grammy nominated artist took to Instagram to share photos of her swollen eye after the show.

“I’m Good,” Rexha wrote, referencing her chart-topping hit with David Guetta.

The Brooklyn-born singer also confirmed she would continue her Best F*kin Night of My Life Tour.

“Although the show ended in an unfortunate way it was still an amazing show in my hometown,” she wrote on Instagram.

“Thank you so Much New York. I love You. The Tour must go on!!! Philly next!”
