Coordinating costumes are all the rage this year. Khloé Kardashian and her boyfriend, Tristan Thompson, celebrated their first Halloween together at a PDA-filled party Sunday, October 30 — and they totally nailed their superhero ensembles.

The Keeping Up With the Kardashians star, 32, and the Cleveland Cavaliers player, 25, dressed up as Marvel Comics characters Storm and Black Panther, respectively. She looked gorgeous in a black leather bodysuit and cape, and completed the superheroine look with silver hair, creepy colored contacts and dramatic black and metallic makeup. Thompson, meanwhile, donned a more traditional action hero look with a muscle jumpsuit and a mask.

Throughout the night, Kardashian documented the celebration with a series of photos and videos shared on her Snapchat account. In one video, the NBA star lifted up his mask and stuck out his tongue to give his girlfriend a big, sloppy kiss. In another racy clip, Kardashian bent over and grinded against her new beau as they danced to the music.

The next day, the reality star shared several photos from the fun-filled night on Instagram. "STORM," she captioned a solo shot that showed off her intricate costume. She then posted a picture of herself gazing into Thompson's eyes, which she captioned with a red heart emoji. (Thompson later reposted one of the photos on his Instagram account, writing, "About last night... 😘🎃👻"

Kardashian also uploaded a controversial group photo of herself, her boyfriend and three of their friends, one of whom was dressed as a Middle Eastern man. Several users commented on the picture to criticize the insensitive costume choice, calling it cultural appropriation. "I love you khloe, but I didn't know my religious/cultural clothing was a costume now! That's @ your friend," one user commented.

Happy Halloween

Us Weekly exclusively reported in September that Kardashian and Thompson (who is expecting a child with his ex Jordy C next month) were an item after they took a romantic trip to Cabo San Lucas, Mexico. She was previously married to retired NBA star Lamar Odom, with whom she reached a divorce settlement on October 21.
