What the hell?! Is Justin Bieber hiding some love bites on his neck with this thick hoodie?

After his third of fourth date with Kourtney Kardashian Friday night at The Nice Guy, we now see The Biebs covering his neck as he heads out for a pressed juice with a pal. Now we would say NO WAY is the pop star, 21, hooking up with the mother-of-three, 36, but Us Weekly would! The mag says Bieber's even bragging about it!

"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," a source tells the magazine.

Seriously?!
