The Real Housewives of Beverly Hills' Erika Jayne is sharing an update on her divorce from estranged husband Tom Girardi. Jayne, 54, confirmed during a Thursday, December 18, appearance on Watch What Happens Live With Andy Cohen that she has filed for legal separation from Girardi, 86, but added, "It's very difficult to get someone who's incompetent to divorce ... I have to ask the conservator." (Girardi was diagnosed with Alzheimer's and dementia in 2021 and placed under his brother Robert's care.) "It's just not that easy," she added.
