Ariana Grande upset at Grammys after haters attack hair on Twitter [again], almost cries: songstress' Red Carpet meltdown comes after viral Facebook rant

Earlier this month, Ariana Grande posted this epic Facebook rant in regards to her "destroyed" Hollywood hair:

Since people give me such a hard time about my hair I thought I'd take the time to explain the whole situation to everybody. I had to bleach my hair and dye it red every other week for the first 4 years of playing Cat... as one would assume, that completely destroyed my hair. I now wear a wig on Sam & Cat. My real hair is back to brown and I wear extensions but I wear it in a pony tail because my actual hair is so broken that it looks absolutely ratchet and absurd when I let it down. I tried wigs, they looked RIDICULOUS. Tried a weave because I am working on a new project and want to try some different looks and literally wanted to rip my scalp off. So as annoying as it is for y'all to have to look at the same hair style all the time, it's all that works for now (AND I'm comfortable for the first time in years).... And trust me, it's even more difficult for me to have to wait forever for my natural hair to grow back and to have to wear more fake hair than every drag queen on earth combined. So PLEASE gimme a break about the hair (or just don't look at me lol). IT'S JUST HAIR AFTER ALL. There are way way way more important things. Love y'all very much.

But the pop sensation's cyber plea couldn't stop the haters from bashing her hairstyle yet again... this time at the 2014 Grammy Awards.

An alleged insider tells E! News' Marc Malkin, "She's still not completely comfortable on carpets and she made the mistake of looking at Twitter. This blogger attacked her dress but also went after her hair and then more people started piling on. It was just mean. Ariana was like, 'Why am I even here?'"

But Grande held her head up high and didn't let the social media bachlash keep her down. The Nickelodeon sweetheart looked gorgeous in a stunning Dolce & Gabbana dress.

"Ariana has learned not to look at Twitter. She's young. She's learning to grow thicker skin," the source reveals.

Do Mstars fans think people should cut Grande some slack over her infamous hair extentions?
