Brandi Glanville is exiting the Bravo reality show after four years, sources told PEOPLE on Thursday.
Glanville could potentially still appear on the show in the future, as previous Housewives Adrienne Maloof and Camille Grammer have done in seasons past.
A source close to Glanville says she was not fired and is deciding whether or not she will return to the show in any capacity.
PEOPLE has confirmed that Kim Richards – who is in rehab after her April arrest for public intoxication – and Yolanda Foster – who is battling Lyme disease – will also not return.
Earlier in the day, the former model hinted about her uncertain future on the series, Tweeting, "I woke up with a sore throat and a HUGE decision to make today! #RHOBH Will let you all know later I promise !!"
Glanville, 42, has clashed with almost every member of the cast, but her feud with Kyle Richards took the spotlight last season as she defended sister Kim amid signs the former child star had relapsed.

Glanville joined RHOBH as a "friend of the Housewives" in season 2 and became a regular the next year.
A mom of two with ex-husband Eddie Cibrian, she has written two books and hosts the podcast Brandi Glanville Unfiltered.
