Add Bebe Rexha to the list of female celebrities being dissed by fashion designers. On a positive note, the singer has the support of her fellow stars.

Rexha, who's up for two Grammy Awards on Feb. 10 – new artist and country duo/group performance – took to Instagram Sunday to say she's having a tough time getting ready for her big night.

“So I finally get nominated at the Grammys and it’s like the coolest thing ever,” Rexha says in her Instagram video. “And a lot of times artists will go and talk to designers and they’ll make them custom dresses to walk the red carpet. … So 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.”

The “I’m a Mess" singer, 29, says she's a size 6-8, and, "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 (expletive) dresses. ‘Cause that’s crazy. … You’re saying that all the women in the world that are size 8 and up are not beautiful, and they cannot wear your dresses.”

In the caption, Rexha added: "If you don’t like my fashion style or my music that’s one thing. But don’t say you can’t dress someone that isn’t a runway size. Empower women to love their bodies instead of making girls and women feel less then (sic) by their size. We are beautiful any size! Small or large!")

She ends the caption with the hashtag #LOVEYOURBODY.

Designer August Getty responded to her Instagram post: “You are beautiful! Every woman of every size is beautiful! Just let me know when I should start sketching.”

Stella Nolasco, who has dressed Beyonce and Eva Longoria, also volunteered, writing, 'I would love to dress you!" (So did Sachin & Babi.)

New York-based women's wear designer Tanya Taylor was also down to dress Rexha, writing, "We would LOVE to design something custom for you!!"

Another designer, Elizabeth Kennedy also raised her hand, noting she had first-hand experience dressing a size 8. “I’d love to make you a dress for the Grammys! I’m a size 8 too, and yes it is a beautiful size.”

And in case you were wondering, yes, Christian Siriano, who came through for Leslie Jones and Megan Mullally when no designers would work with them, has also volunteered his services to Rexha. "Thanks everyone for the love!" the "Project Runway" alum tweeted after multiple commenters tagged him. "We have dressed @BebeRexha a few times and would love to do it again!"

Rexha also garnered the support of her fellow celebrities on Twitter.

"(Stylist) @adenarohatiner has no problem dressing my size 8 (butt)," "Big Bang Theory" star Mayim Bialik tweeted Monday. "I’m sure she’d love to hear from you. Sending you a size 8 hug."

That same day, Tyra Banks recalled a time the two crossed paths in Toronto, when she learned just how "special" Rexha is.

"Those designers that don’t wanna dress U are DUMB," Banks wrote. "U my dear @BebeRexha are pure genius...H2T - head to toe!"

"Bleeding Love" singer Leona Lewis responded: "I LOVE U for this @BebeRexha..." She called the situation "outrageous & damaging to women’s body image!"

Rexha isn't the only star to face a fashion gauntlet.

Megan Mullally took to Instagram in December to announce she is hosting the Screen Actors Guild Awards and that, "looks like i will be buying my dress online though, as per my usual, even though there is literally a 100 percent chance that i will be on camera, because I’M HOSTING IT. designers do not send me dresses."

And when her "Ghostbusters" movie came out in 2016, "SNL" alum Leslie Jones had a similar complaint, "It's so funny how there are no designers wanting to help me with a premiere dress for movie. Hmmm that will change and I remember everything."

For both Jones and Mullally, "Project Runway" alum Christian Siriano jumped in to offer assistance.
