Michael Costello, a former contestant on Project Runway, bought a dress from up-and-coming designer Maxine James. She was miffed when he a posted a nearly identical version on Instagram, without crediting her.

She responded with a long post, Eurweb reports: "As a designer [you] should know first hand how heart breaking it is for ppl to take something you worked so hard on �..It's like why? Who does that?"

In response, Costello allegedly lashed out at her, according to a screenshot purportedly of his Instagram page. "Your just probably a dumb n-er defending her," the screenshot shows Costello's account saying. "I am royalty b-h! I dressed Beyonc�! Who are they gonna believe!"
