Halsey Says She "Can't Imagine a World Without" Evan Peters on His Birthday

Ever since Halsey officially confirmed her relationship with American Horror Story actor Evan Peters on The Ellen DeGeneres Show this past October, we can't seem to get enough of them. I mean, their New Year's jet-ski trip looked all kinds of fun, and they sure do make an epic Sonny Bono and Cher (you can catch a glimpse at those costumes above).

Halsey, who released her third studio album, Manic, on Jan. 17, wished her boyfriend a happy 33rd birthday with a sweet Instagram post. The caption read, "happy birthday darling. I can't imagine a world without you in it." The black-and-white pictures she shared, which you can see ahead, appear to be taken photo-booth style.

According to Us Weekly, the two have moved in together. We love their love!
