Halsey and Evan Peters certainly know how to make an entrance.

On Saturday, the pair made their red carpet debut dressed as Sonny Bono and Cher for the Hollywood celebration of “American Horror Story’s” 100th episode.

Halsey, whose relationship with Peters is now Instagram official, rocked a colorful polka dot dress, while the “American Horror Story” actor, 32, paired his white jacket and slacks with a matching printed shirt.

The singer, 25, and Peters first fueled romance rumors in September, when they were spotted getting cozy at Six Flags. Over the weekend, Halsey shared a photo of the two with her 16.8 million Instagram followers, captioning the snap: “Resident goths.”

Halsey previously dated rapper G-Eazy. As for Peters, his ex-girlfriend and fellow “American Horror Story” star, Emma Roberts, also attended Saturday’s bash. The 28-year-old actress was photographed at the event with co-star Sarah Paulson.
