Rachel Roy stirred the Beyhive -- and now she may be feeling the sting.

The 42-year-old fashion designer, who Beyoncé fans have accused of being the "Becky with the good hair" mentioned in the singer's "Lemonade" visual album, canceled a public appearance on Monday following the weekend's drama.

Roy was supposed to speak at a seminar called "Mastering Your Métier" in New York City, but organizer Neuehoise NYC confirms to ET that Roy pulled out of the event due to "a personal emergency."

Beyoncé's "Lemonade" album deals with themes of marital infidelity and, in one track, "Sorry," the 34-year-old pop star sings, "He only want me when I'm not there / He better call Becky with the good hair."

Shortly after the "Lemonade" premiered, Roy captioned a photo on Instagram, "Good hair don’t care, but we will take good lighting, for selfies, or self truths, always. Live in the light #nodramaqueens." The Beyhive quickly made the connection and swarmed.

This isn't the first time people have speculated about Roy's relationship with Jay Z, either. In May 2014, it was reported that Solange Knowles yelled at Roy before the infamous elevator incident at the Met Gala.

Roy has since made her Instagram account private. On Twitter, she wrote, "I respect love, marriages, families and strength. What shouldn't be tolerated by anyone, no matter what, is bullying, of any kind."

"Lemonade" was packed with personal insights about Beyoncé and Jay's relationship. Check out five of the most intimate moments in the video below.
