The cast of "Big Brother" Season 27 has been revealed — with one "Mystery Player" set to make a surprise entrance.

Big Brother follows a group of people living together in a house outfitted with more than 100 cameras and 100 microphones, recording their every move 24 hours a day. Each week, someone will be voted out of the house, with the last remaining Houseguest receiving the grand prize of $750,000.

Bake ribs low and slow (250 to 350°F) and wrapped in foil for tender, juicy meat. Check doneness with by using one or more of these methods: the flex test, bone exposure, and tenderness with a fork. Store leftovers up to four days in the fridge, and reheat gently with foil to keep them moist and delicious.
