Who will be vying for $500,000 on Big Brother?

CBS has announced the 16 houseguests who will be competing for the grand prize this summer, and compared to previous cycles, it's a much younger cast. They range in age from 22 to 37 (with the majority of the houseguests in their 20s) and come from all walks of life, from a lifeguard and a pageant consultant to a pizza delivery boy and a bartender. Past winner Rachel Reilly's sister is also among the group.

Sixteen houseguests matches the total number of competitors for cycles nine and 14, but host Julie Chen has teased that there may be more houseguests than ever this summer, which begs the question: Will more people be incorporated into the game? If so, how?

On June 19, two twists were revealed by CBS: Instead of two nominees, three houseguests will be up for eviction, and America will vote for the Big Brother MVP of the week, which has powers that will likely be revealed when the Big Brother kicks off.
