Nothing gets the blood boiling like an athleisure wear feud.

Beyoncé unveiled her new athletic clothing line, Ivy Park, on Thursday, a 200-piece collection that will hit stores on April 14. But one stray tweet may have sparked the biggest war the world of yoga pants and loose-fitting tank tops has ever seen.

One Twitter user pondered, "Is Ivy Park supposed to be like Lululemon?" to which the clothing company -- who wasn't even mentioned in the tweet -- replied, "They do say imitation is the best form of flattery. Maybe Beyonce is so Crazy In Love with our brand, she made her own."

Lululemon continued responding to people who were comparing the two lines, apparently thinking it was all in good fun. "We don't plan to bow down to the Queen B when it comes to workout gear, but you know we're going to keep buying her albums," the Lulu social account boasted.

Before realizing they had made a big mistake. HUGE.

Because the BeyHive never forgets, and Lululemon immediately began backtracking on the shade and claiming they meant "no harm."
