The rumour mill has been alight with whispers of a tryst between 36-year-old Kourtney and 21-year-old casanova Justin Bieber.
The twosome were first spotted getting cosy at Kendall Jenner’s 20th birthday party, before they were seen on what looked like a date.
"Every time Kourtney and Justin are together they're extremely flirtatious," an insider told Us Weekly.
"They text each other all the time."
One person who’s sure not to be impressed is Kourtney’s ex partner Scott.
The former long term couple, who share children Mason, Penelope and Reign, split in June.
And now it looks like Justin may have swooped in, and he apparently has no qualms about it.
The What Do You Mean hit-maker took to Instagram to share a snap in front of a mystery woman, captioning the picture:‘Lord knows’.
Scott is known for naming himself ‘the Lord’, leading many fans to believe this was a direct dig at the father-of-three.
He has so far kept a ‘lord-like’ silence on the topic.. we’ll see how long it lasts.
