The 19-year-old model faces legal action after posting a quote by Molomo, from her book "Say What's Real", on Instagram without attributing the words to the writer, reported the New York Post.
The text, which has since been deleted, went on to be published in several publications including Teen Vogue magazine and Us Weekly after it was assumed it was a dig at pop star Justin Bieber - who she was previously rumoured to be dating - following his feud last month with his ex-girlfriend Selena Gomez.
According to documents obtained, Molomo has sent a cease and desist letter to Baldwin, which means if she fails to take action the author has a right to sue her unless she apologises and refrains from copying her work.

Baldwin could be liable to pay the author damages of up to USD 150,000.
The document also states that the blonde beauty should "make a social media post apologising for stealing Ms Molomo's content and fraudulently passing it off as your own."
A spokesperson for the star is yet to comment.
