Taylor Armstrong had a "catastrophic meltdown" during a recent weekend spa getaway in Ojai, California, which has left her fellow Real Housewives fearing for her future if she doesn't seek treatment for her drinking, RadarOnline.com is exclusively reporting.

Multiple sources tell RadarOnline.com that Taylor's behavior, which was all caught on  camera, was out-of-control and frightening to witnesses and was fueled by the amount of alcohol she drank during the trip.

Looking like she brought just about all her worldly belongs with her, Renee Zellweger arrived in Ojai, CA Fri, in advance of her friend Reese Witherspoon's wedding, and RadarOnline.com has the pictures.
