Halsey and Evan Peters, recently, surprised everyone when they appeared together in their Halloween costumes. The two celebrities dressed up as Sonny and Cher during the American Horror Story event earlier this week.

Upon witnessing the two together in their unique get-up, a lot of reports followed speculating that Halsey and Evan Peters are now getting more serious. Although no words were heard from the celebrities then, new information emerged as the Closer artist seemingly confirmed the relationship.

According to People, Halsey surprisingly "confirmed" the dating rumors when she referred to the actor as her "boyfriend." During an interview on The Ellen Show, Ellen DeGeneres showed the picture of the couple in their Halloween costume. She, then, asked Halsey who is the guy beside her, pointing obviously to the AHS actor.

The singer responded shyly and told everyone that it's Evan Peters. But, before the interview moves forward, a staff of the show pranked and surprised Halsey from her seat.

When everyone settled down, the Boy With Luv singer told Ellen that she tricked her with "that boyfriend question" to surprise her. She further contended that she doesn't know what's scarier: the jumping staff beside her or to talk about her "boyfriend" in the interview.

These statements of hers immediately confirmed that she and Evan Peters are now in a relationship. While most of the fans have been shocked by the revelation, others attested that the two celebrities have been seeing each other for a couple of months now.

Metro recently reported that Halsey and Evan Peters were first "romantically linked" in September after they were seen publicly, holding hands and sweet with each other. As per sources, there were a lot of "eyewitnesses" at the Six Flags Magic Mountain, a theme park where the two were seen being romantic and flirty with each other.

Many reports have noted that the two celebrities just came out from their respective relationships; Evan Peters, from his relationship with co-star, Emma Roberts, and Halsey from hers with Yungblud.

Evan and Emma's relationship was a long-term one. Many fans were surprised when the two called it "quits" -- for real, this time -- in March. As for Halsey and Yungblud, no confirmations were made to the public about their rumored relationship.

So far, these are the only details that have been shared about Halsey and Evan Peters' relationship with each other. Fans are positive, though, that more updates will follow in the next few weeks given that the relationship is now confirmed in public.
