Kourtney Kardashian hasn't publicly been in a relationship with 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 are 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. 

Just hours after Kardashian posted the photo, Moakler posted a selfie of her own. 

And while the post itself was unsuspecting, it's what happened in the comments that has people talking. According to E! News, Moakler liked a clearly shady comment about Kardashian. "Shhhhiiiii that broad don't got nothin' on you. Travis downgraded big time," the Instagram user wrote on Shanna's post. Yikes. 

It's important to note that Moakler, Barker, and Kardashian go back years, with Moakler and Barker's children having played with the Disick children in the past. Could this relationship simply be too close to comfort for Moakler?
