Andy Cohen’s holiday special “O Come OG Faithful,” starring all the original housewives from the hit franchise, had a glaring omission – Lisa Vanderpump.

And in a twisted move, her The Real Housewives of Beverly Hills costar, best friend turned nemesis and Kyle Richards, is headlining the special!

“Watch What Happens Live with Andy Cohen is filled with the holiday spirit when O Come OG Faithful airs live on Thursday, December 20 at 11 p.m. ET.,” Bravo announced on Friday, November 30, adding that Vicki Gunvalson, NeNe Leakes, Ramona Singer, Bethenny Frankel, Teresa Giudice and Richards will all “deck the halls and spill some tea."

Vanderpump's absence doesn't come as a surprise to Breaking Celebrity News readers. Though she publicly claimed she's unsure about her future with the show, Breaking Celebrity News exclusively reported the 53-year-old mogul was leaving the show that made her a beloved reality TV star after too much drama with costars and her brother's death pushed her over the edge.

She will appear in several episodes of the upcoming season, but stopped filming mid-production.

“She has no plans to return to the show,” a show insider told Breaking Celebrity News. “But who knows what the future holds.”
