According to reports, Beyoncé is moving on from Adidas with her Ivy Park brand after the two sides had creative differences about the direction of the activewear line. 

The partnership between Mrs. Carter and Adidas was struck in 2018 where she relaunched the activewear line and developed new footwear and apparel for the brand as well. But major creative differences have prompted Beyoncé to move on from her situation with the "Three Stripes" and launch the brand for a third time. 

Ivy Park debuted in 2016 as a 50-50 venture with Topshop but after the deal ended two years later, Beyoncé gained full ownership of the brand. There's no word yet on any potential partnerships for Ivy Park whose last collaboration with Adidas debuted in January.
