It could be 100 degrees outside, but it still wouldn't feel like summer without Big Brother. But it's finally time to bust out the swimsuits and snow cones, because Big Brother 21 kicks off with a two-night premiere on Tuesday, June 25 and Wednesday, June 26 at 8/7c. And what's really exciting is that we finally have our first info on the 16 new houseguests moving in to vie for the $500,000 grand prize.

A few of the most notable new recruits include a public health analyst who lists "spending other people's money" as her favorite activity, a server who's worried about not being able to get his "daily watermelons," a preschool aide who once called the cops on her parents because she didn't get her way, and a college student who owns 10 pairs of Crocs.

Despite rumors to the contrary, there are no returning houseguests announced to be participating in this season. But as always, expect the unexpected with Big Brother, so who knows what twists the show will throw our way once BB21 officially kicks off.
