Hours in the makeup chair? Demi Lovato and Wilmer Valderrama paid homage to the Day of the Dead (Mexican holiday Dia de los Muertos) while throwing a Halloween bash for their friends on Thursday, Oct. 30.

"Happy Halloween from @wilmervalderrama and I…" Lovato, 22, captioned an Instagram snapshot of the duo on Halloween. The "Really Don't Care" singer and That '70s Show alum, 34, looked intense while wearing sugar skull face makeup. Lovato donned a black spiderweb on her forehead, added a pop of red lipstick, and wore a red flower headpiece.

Valderrama looked even more serious while in character. He stuck with just black and white makeup, wore a sombrero, and clutched onto maracas.

The on-again, off-again lovebirds have never confirmed their relationship, but have supported each other over the years. Most recently, Valderrama made a surprise appearance at Lovato's Santa Monica, Calif. concert on Oct. 8. The duo took a picture together backstage with Blink-182 drummer Travis Barker at the time.
