Harry Styles was guest-hosting James Corden's 'Late Late Show' last night and had his former flame Kendall Jenner in for a game of 'Spill Your Guts or Fill Your Guts'.

If you haven't watched the game before, it sees two people ask each other a series of delightfully awkward questions. Each face a choice, either answer truthfully or eat whatever is in front of you, with the likes of cod sperm and a salmon smoothie some of the disgusting options on offer for Harry and Kendall.

Some of the questions include Styles asking Kendall to rank the parenting skills of her famous siblings (which she does) while Kendall gets to ask Harry which one of his songs were about her.

Kendall also comes very close to revealing a "surprising celebrity that slid into her dm's" and now we must know.
