The May-December couple has been linked together since last November. Corey -- a road manager with Justin Bieber's manager Scooter Braun's SB Projects -- obviously has the stamp of approval from Kris's children, including 36-year-old Kourtney, who sent him a cute birthday message on his big day.
"Happy Birthday @coreygamble!" Kourtney wrote next to an Instagram picture of him snuggling up to two of her kids, 3-year-old Penelope and 5-year-old Mason. "A grandpa never looked so good."
"My mom is living the good life right now. When I found out she was dating, or even texting back and forth, it was so weird to see her giggly," she said. "I'm like, 'How do you flirt? Like, what do you guys say?' And it is disgusting. It's awkward."
"Why is a 32-year-old, or whatever he is, why is he talking to a 50-fabulous-something woman?" she added, calling out their 25-year age difference. "That's just -- and I say it to her all the time -- weird. Hearing them have sex is wild and I'm traumatized."
