Amber Rose and rumored boyfriend Val Chmerkovskiy had a spook-tacular Halloween together this year. The pair partied in Hollywood together on Sunday along with a group of their friends.

Rose, 33, and Chmerkovskiy, 30, both dressed up as dead characters as the mother of one donned a sexy mermaid look with a bejeweled purple bra and sequined high-waisted green skirt. Meanwhile, the Dancing with the Stars pro was a member of the zombie-esque Three Musketeers with his friends, complete with elaborate black and white face makeup and fake blood.

“We take Halloween seriously,” Rose captioned a group photo on Instagram and Twitter Monday. In her PDA picture, Chmerkovskiy rested his head on Muva’s chest and placed his hand on her derriere.

The budding couple first fueled romance rumors a couple of weeks ago after they were spotted getting friendly at her 33rd birthday party.

“They were giggly and seemed very comfortable together,” an onlooker shared to PEOPLE.

Although Rose was eliminated from DWTS on week 6, the dancing competition introduced her to her former pro partner Maksim Chmerkovskiy‘s younger brother.

“They met through Maks and really like each other,” a source previously told PEOPLE. “It’s very new, but it’s going well.”

While Rose has yet to comment on the dating rumors, the Ukrainian dancer joked to ET: “I’d make a cute couple with a lot of people, you know what I’m sayin’?”
