Kris Jenner and boy toy Corey Gamble met up with pal Lance Bass and his partner Michael Turchin Saturday night for a dinner date at Mastro's steakhouse in Thousand Oaks.

Kris was dressed to the nines, as usually, in a black-and-white ensemble. And this time, it was her boyfriend Corey hugging it out at the end of the night -- with Lance Bass. The night before, Kris embraced her ex-hubby, now Caitlyn Jenner, at daughter Kylie's 18th birthday party at Nobu Malibu. And even bigger news ... the pair took their first selfie together!!! Well, first selfie as Caitlyn. Big news, people!
