Big Brother

When Big Brother 12 premieres on July 8, viewers will meet a number of cast members.

But none of them will be able to top the story of Kathy Hillis. A 40-year old deputy sheriff from Arkansas, she opened up to Zap2it this week regarding her reason for coming on the show:

"When my grandma was terminally ill, we used to watch Big Brother together... when she passed away, I started applying. I applied for five years and now I made it on."

incredibly, Kathy is also a cancer survivor. She was told she'd never see the age of 30, but is alive and well over a decade later.

As for her strategy? "[I'm] going to have fun and going to be myself" she said, adding that she'll tell the truth about her occupation.
