Sources told Page Six that cast members from Bravo’s upcoming “The Real Housewives of Salt Lake City” were partying at Sundance in nearby Park City, Utah.

A spy at a performance by Lil Jon and Post Malone told us, “The housewives of Salt Lake were filming several of the newly cast ladies at the party,” adding that they were “dancing front row” and “gallivanting at a VIP table.”

Observed our source, “The blond ladies definitely looked like a fun group.”

Andy Cohen announced the Salt Lake show in November.

Lil Jon was also celebrating his birthday at the Park City Live Snow Fest, and was “presented with a huge 24-karat- gold-coated birthday cake onstage, then Post Malone popped on to surprise him.” Jon was spinning as a SKAM Artist DJ.
