He’s famous for his wild party ways and teen conquests, whilst she’s more into yoga retreats and staying in with her three children.
No, we’re not talking about Scott Disick and Kourtney Kardashian - we're talking about 21-year-old Justin Bieber and 36-year-old Kourtney.
Sources have confirmed to US Weekly that the pair are ‘definitely dating’, revealing:
“Justin bragged to friends recently that he has been hooking up with Kourtney Kardashian.
With a second source adding: “Oh, yeah, that’s definitely happening and has been for some time now.
"Every time Kourtney and Justin are together they’re extremely flirtatious. They text each other all the time.”
In October, Justin and Kourtney, who split from long-term partner Scott in July, had dinner at Nice Guy in Hollywood before going to the ‘Halloween Horror nights’ attraction.
“When he was there with Kourtney, he was such a gentleman and so nice and respectful,” a source told US Weekly.
“He was definitely trying to impress Kourtney and act more mature.”
Interesting...we wonder what Scott has to say about all this?
