The actress, 15, received cruel comments on social media after she presented the best female hip hop artist award to Megan Thee Stallion during the virtual BET ceremony, with trolls specifically criticising her hair and teeth.
Martin then shared a video on Instagram in which she appeared to shed tears over the comments and apologise to anyone that she had “offended” - before blowing her nose on a $100 bill.
"So, I was on Twitter and a lot of people have been addressing my hair, talking about my hair and how it looks like a grandma's wig," she said, before pulling on her hair.
She then added “they’re talking about my veneers” before taking out a clear brace, adding: “This don’t look like a veneer to me.”
“I’m sorry to anyone that I offended or haven’t gotten to my expectations about how I’m supposed to be,” she continued, wiping her eyes in mock concern for the trolls.
“I never want to hurt anyone’s feelings or have anyone worried about what my decisions are.”
She was then handed a $100 bill and blew her nose on the note, before reminding viewers: “We are in quarantine and we’ve got more things to focus on than just my hair.”

She finished her video with a call for “justice for Breonna Taylor,” the 27-year-old nurse who was shot dead by police at her home in Louisville, Kentucky, in March.
Martin also addressed the trolling on Twitter, writing: "Sorry some of y’all don’t like my hair. Or teeth ... which are my actual teeth btw. Good thing I don’t put my effort into trying to please everyone. I like it.
"Chile I’m 16 this year, let me live. I’m trying to stay sane in quarantine. Enjoy the #BETAwards."
