Peters was in a long-term, on-and-off relationship with actress Emma Roberts since 2012. The couple got engaged in 2013, but they had a rocky road ahead. They broke up for the first time later that year, and although they got back together, they called it quits again in 2015. They reconciled, split up once more a year later, and then stuck it out for three more years. But it looks like Peters and Roberts have finally gone their separate ways.
The couple broke up for good in early 2019, and Roberts is now reportedly dating Triple Frontier star Garrett Hedlund. Interestingly, unlike Peters, Roberts is slated to appear in the ninth season of AHS. She also appeared alongside Peters in earlier seasons, and despite their tumultuous relationship, the couple always remained professional on set. Perhaps the post-break up awkwardness made Peters hesitant to jump right back into working with her. This is why dating a coworker is always a risky move.
