Now, according to Us Weekly, the pair are 3000% official.
"They're legit. They're a full-on couple," a source revealed. "Kendall has been going to a lot of his games and they have been enjoying time at home when Blake is in town. They're good."
The pair have been spotted on multiple occasions together, always smiling and always getting super cuddly with each other.
They even just took a trip together to Universal Studios Halloween Horror Nights with Kylie Jenner and her BF Travis Scott. A source then told People that "[Kendall] thinks [Blake] is dorky and funny, but also cool and sexy — he has a certain attractive 'swagger,'" and that "they are seeing each other more, and Blake is doing everything in his power to make Kendall his girlfriend."
