Kris Jenner has thrown the rumour mill into overdrive after hinting that she is engaged to boyfriend Corey Gamble.

The Kardashians momager sat down with James Corden on Tuesday's (07Aug18) episode of The Late Late Show, where she agreed to take part in the programme's infamous Spill Your Guts or Fill Your Guts challenge, which forces stars to eat something disgusting if they fail to answer a revealing question.

And for Kris, 62, it seems she would rather chow down on a bowl full of dried crickets than address her four-year relationship with toyboy Corey after she was probed on the matter by show host James.

"Kris, you've been spotted wearing a massive diamond ring on your wedding finger," the 39-year-old asked. "Are you and Corey Gamble engaged?"

Laughing, the Keeping Up with the Kardashians star, who started dating the tour manager in November 2014 following her previous marriages to Caitlyn Jenner and the late Robert Kardashian, moved towards the bowl of crickets and smiled: "No, I'm not going to answer" as the crowd whooped and cheered.

The camera then panned to 37-year-old Corey, who looked on from the wings with a surprised look on his face.

But the real revelation came when James jokingly implied that the large, diamond-encrusted ring on her finger was an answer in itself.

"This isn't the ring," Kris shot back, before realising her mistake and roaring with laughter. "But there is a ring?" James responded, astonished, as the crowd cheered once again in approval.

Earlier on in the game, the mother-of-six was forced to sip a sardine smoothie after refusing to confirm which of her daughters she would drop from their titular reality show if she had to choose.

"I'm not gonna turn on one of my girls," she maintained. "Those are my babies!"
