Did Scott Disick confirm Kourtney Kardashian hooked up with Justin Bieber?

hey were rumoured to have secret hook-ups, but now it looks like Scott Disick has thrown some serious shade over his ex Kourtney Kardashian's rumoured fling with Justin Bieber.

The 'Lord' has poked fun at the rumours that were swirling following their split after nine years together.
Scott joined the family for a game of Cards Against Humanity while the Kardashian family were on holiday in Vail, Colorado.

In a preview for Sunday night's show of Keeping Up With the Kardashians, Kourtney and Scott were playing with Kendall and Kylie Jenner and the teen's then-boyfriend Tyga.
For Kourtney's round, her query was 'Why am I sticky?'

The group all put their white cards in, which they use a word or a phrase to best answer Kourtney's question.

As the mother-of-three answers the question, which include 'your weird brother'. She also reads a card that reads: “Justin Bieber”.
When she reads that out, the group erupts with laughter and Kourtney is a bit bashful.

“Scott feels she’s doing this to get back at him and get revenge,” they said.
“He feels he has to take it and can’t say anything after all he did to her, but he thinks it’s dumb and immature.”
