After breaking things off with Cazzie, Pete got together with Ariana in May 2018, and a few weeks later, the two were engaged. However, their romance was short-lived as they broke up in October 2018. According to People, they split after realising "it was way too much too soon." Ariana later referenced the breakup in her Mean Girls-inspired "Thank U, Next" music video, where she dedicated a page in her burn book to Pete and made a reference to his BDE, writing, "HUUUUGE."
