Big Brother season 15 cast
Welcome to the Big Brother
The season 15 houseguests entered the Big Brother
house just a few days ago and wasted no time making themselves at home poolside. Here's your first look at the group.
But the 16 houseguests – the largest cast in the CBS reality show's history – will not be spending all summer relaxing under the sun.
In a new twist, the show's two nomination chairs have been replaced by a "nomination couch" to make room for a third nominee's eviction every week. And a new power will be in play this summer as fans vote weekly for a "Big Brother
MVP," whose special power will be explained by host Julie Chen.
"It is going to be an entirely new game. I don't even know if I could play it," says season 13 winner Rachel Reilly, whose sister Elissa Slater will be competing this year
. "There is no way for anyone to float through."
Endurance will also come into play more than ever, as the houseguests settle in for a record 100 days.
"I think it is going to be really hard for the houseguests. The season I won I was in for 76 days and that was forever," Reilly tells PEOPLE. "As a fan I am so excited for two extra weeks of Big Brother
, but I feel bad for my sister. It is going to be insane."
