The couple have been dating since meeting via mutual friends over the summer and it certainly seems to be serious as Corey's met Kris' kids and grandkids and appeared in Keeping Up With The Kardashians.
Kris' daughter Kim Kardashian West, 35, recently said that Corey, 35, had been good for Kris as he made her happy.
"It's been so much fun just to see my mum happy," she told People. "My mum has had such a hard year and I think it's been refreshing to see her have a good time."
Kris split from husband of more than 20 years, Bruce Jenner, in 2013. Then, earlier this year, Bruce announced that he was transitioning into a female named Caitlyn.
