They may have been in character as Storm and Black Panther for the evening, but Khloe Kardashian and Tristan Thompson couldn't conceal their own budding romance.
During a Halloween bash Sunday night, the 32-year-old reality star got into character as the silver Marvel superheroine, complete with frost white hair, glittering face makeup and ice blue contacts. The Cleveland Cavaliers pro followed his leading lady's cue, donning a full bodysuit and face mask to complete the comic book couple.
"Storm and my boo black panther," she explained with a Snapchat selfie.
The term of endearment wasn't the only signal of their hot and heavy romance. Next, the pair grinded to the music and captured their close moves on camera. To top off Kardashian's Snapchat story with a grand finale, Thompson lifted his mask and she went in for a steamy French kiss complete with a ton of tongue.
It definitely looks like their relationship has progressed since they jetted off to Mexico together in early September. A month later, the reality star was spotted supporting her man on the sidelines of his basketball games and a source confirmed to E! News that the two were not seeing anyone else.
"Khloe and Tristan are doing really well. They are exclusive," the insider said. "There is a lot of chemistry between the two of them and they are happy together."
In fact, Kardashian has rearranged her wardrobe to accommodate her trips out east.
"She had a few clothes shipped to Ohio because she plans to keep flying back and forth during the season," our source explained.
Meanwhile, it seems the athlete has mom's stamp of approval.
"They are really cute," Kris Jenner told E! News. "You know, she's having a good time. He seems like a really nice guy."
