Hilton's aunt checks into rehab

It is not clear if the 47 year old is seeking treatment for booze issues, but her sister and co-star Kyle Richards accused her of being an alcoholic on last season's finale.

Actor Eddie Cibrian's ex-wife Brandi Glanville also accused Richards of being "wasted out of her f**king mind" during a Real Housewives episode.

In an episode that aired in November (11), Richards revealed she was taking anti-anxiety and antidepressant medications, along with an anti-seizure medication which can be used to treat alcoholism.
