Kourtney Kardashian hasn't publicly dated anyone since the father of her children, Scott Disick. So if she's posting a mate, you know it must be real. On Tuesday, she posted a photo confirming the rumors that she's been dating Travis Barker. In it, the two hand in hand, with Barker responding with a black heart emoji. 

And while thousands of fans, friends, and family expressed their excitement and support, there were some who weren't so overjoyed. One of those people, was Barker's ex, Shanna Moakler.
