The 29-year-old posted a video on Instagram, in which she revealed she was finding it difficult to find a dress for the upcoming Grammy Awards ceremony.
The star, who is nominated for two gongs, made it clear that she felt her size was a factor, accusing top designers of snubbing her because she's a six to eight and, therefore, "too big" to wear high end looks.
"A lot of times artists will go and talk to designers, and they'll make them custom dresses to walk the red carpet... I had my team hit out a lot of designers, and a lot of them do not want to dress me because I'm too big," she said. "If a size 6/8 is too big then, I don't know what to tell you. Then I don't want to wear your f**king dresses... To all the people that said that I'm thick... f**k you, I don't want to wear your f***ing dresses."
The rant prompted several celebrities to salute "The Way I Are" hitmaker, with Demi Lovato and Adam Lambert among those taking a stand with her, while "Project Runway" mentor Christian Siriano sent words of encouragement via social media and offered to dress her for the Grammys. He wasn't alone - Bebe also got offers from Michael Costello, August Getty, Tanya Taylor, and Elizabeth Kennedy.
The reaction was not something Rexha expected.
"I really just wanted to share my story and how frustrated I was," she tells People. "I never expected to receive the amount of love and support that I did."
Though she has yet to settle on a look for the Grammys, she knows what type of outfit she is looking for, telling the publication, "I just need to feel good!".
