A Deuxmoi post said the Grammy-winning singer's name is being discussed for the next Bravo season, potentially reviving attention on her past feud with former cast member Brandi Glanville.
Rimes married Eddie Cibrian in 2011 after their affair ended his marriage to Glanville, and that fallout previously played out publicly and on the show.
Glanville has not commented on the latest speculation, though in 2014 she said she was open to Rimes joining RHOBH; fans online were split over the rumoured move.
Despite their truce, is Brandi Glanville's latest tweet bait for a televised showdown with LeAnn Rimes?
After rebuilding her career, why would LeAnn Rimes risk it all to join a notoriously dramatic reality TV show?
Is the LeAnn Rimes casting rumor a calculated PR move or just baseless gossip from an anonymous source?
