Mema from 'Hollywood Hillbillies' -- Hospitalized During Media Tour

Being a reality star might be too much work for Mema from "Hollywood Hillbillies" -- the 70-year-old had to be rushed to the hospital while she was in NYC to promote her Reelz TV show.

We're told Mema was leaving her hotel Thursday when she fell ill. Her grandson and manager David Weintraub found her walking out of the lobby to hail a cab that would take her to the ER.

Mema's temp was 104. She spent the night at the hospital and doctor's think the 12-hour-days media tour was just too much for her.
