'Big Brother 16' twist: 2 Heads of Household, 4 nominees every week and a new competition

big-brother-16-julie-chen-CBS.jpgOn Wednesday's (June 18) episode of "The Talk," "Big Brother" host Julie Chen revealed the twist for the upcoming Season 16 of the long-running summer reality show.

The twist is that not one, but two houseguests will win Head of Household every week. That means that every week, four people will be on the block! And there's more, because there's a brand-new competition called "Battle of the Block," which means being HOH does not always mean you are safe.

Plus, the viewing audience will have even more power than ever before as Team America.

There are no other details offered about the new HOH battle or exactly how nominations will work -- is it collaborative? does one HOH go first, then the other? Do they alternate? -- but we expect Chen will fill us in next week during the two-night premiere on Wednesday, June 25 and Thursday, June 26 on CBS.

What do you think, "Big Brother" fans?
