Here's why the WWHL host and the RHOBH ladies are beefing.

Andy Cohen has a pretty unbreakable bond with The Real Housewives of Beverly Hills ladies — so it was a shock to see that they are playing opposite each other on an upcoming episode of Family Feud.

The Watch What Happens Live with Andy Cohen host posted that his Radio Andy family united against their West Coast nemeses in what looks to be a very promising episode. "Coming soon: [Radio Andy] vs [RHOBH] on The Feud! Man was this fun," he wrote alongside a photo of him with Bevy Smith, Flipping Out's Jeff Lewis, Amy Phillips, and John Arthur Hill. On the opposite side of the room were Teddi Mellencamp Arroyave, Dorit Kemsley, Lisa Rinna, Kyle Richards, and newcomer Garcelle Beauvais.

Kyle commented on the post, "This was so fun!!!!" And Dorit agreed: "Such a blast!" The Real Housewives of Orange County alum Jeana Keough's eldest son, Shane Keough, proposed another episode idea in the comments: "[Housekids] got next [Andy Cohen]."

No word on when the episode airs yet, but we'll be watching!
