Momager Kris, 59, plants a huge smooch on toyboy beau Corey Gamble, 34, as she celebrates her new magazine cover with the Kardashian-Jenner gang

Fans were initially sceptical of their relationship due to a 25-year age gap.

But Kris Jenner, 59, proved there's no shortage of passion between her and her 34-year-old toyboy boyfriend Corey Gamble as they shared a smooch at the dinner table at Nobu restaurant in Malibu on Monday night.

The showbiz momager was spotted planting a wet smacker on her music executive boyfriend's lips as she celebrated her new Haute Living magazine cover alongside her famous family at a special bash held in the upmarket venue.

The pair naturally couldn't resist documenting the intimate moment on camera, taking a snap of their kiss for social media posterity.

Their steamy relationship has been well documented on the family's E! reality show, with Kris' children Kim and Khloe Kardashian repeatedly discussing how mortifying their mother's bedroom antics are.

'It’s disgusting I don’t need to hear,' Khloe said. '[Kim] tells me about the squeaking, it’s disgusting.'
