We're about to barf in Birkenstocks (they're shiny, white and new, so it takes something totally barftastic to make us feel like we might risk ruining them). Get this -- French Montana (Khloe K's ex) and Dorothy Wang (of Rich Kids of Beverly Hills) are hooking up! Yes! They were caught "cozying up!" Who the hell would want to cozy with French??!!!

As Khloe was busy "cozying up" to new beau James Harden, apparently Dorothy was jumping on the French wagon. The two were spotted together at the Red White and Bootsy pop-up party at Nobu Malibu on the 4th of July, according to Dish Nation. "French and Dorothy were pretty much inseparable throughout the night. Wherever he went around the party, she was not far behind," a source tells the show.

And Khlo's sis Kylie was at the party so we're SURE she's already told Khloe about French's rebound. Hey, we've got a feeling Khloe doesn't give a SH*T! She's got James Harden! Waaaay better!

We're gonna reach out to Dorothy's pals EJ Johnson, Morgan Stewart and the rest of the team, stat, to see about an emergency intervention. #DorothyDeservesBetter Stay tuned ...
