What happened during the 'Big Brother' season 25 premiere? Everything to know

Spoiler alert! This following post discusses events that occurred during the "Big Brother" season 25 premiere on Aug. 2.

The hit CBS reality show "Big Brother" returned with a bang Wednesday night.

To kick off its monumental season, "Big Brother" not only nominated four houseguests right off the bat (before even crowning a Head of Household), but it also announced possibly the biggest twist in the show's history (no, we're not exaggerating). Near the end of the episode, host Julie Chen Moonves revealed that "Survivor" legend Cirie Fields would be the unprecedented 17th houseguest this season, joining her son, Jared Fields, who is also on the cast.

So when will the show air its next episode?

Sixteen new houseguests entered the house during the "Big Brother" season 25 premiere. But instead of a Head of Household competition, the show hosted four separate nomination challenges, with the four losers automatically going on the block.
