'Big Brother' host Julie Chen.

Along with host Julie Chen, some familiar faces will be returning to the 'Big Brother' house.

CBS has announced today that this summer's edition of 'Big Brother' will be an All-Star version which will bring back contestants from previous seasons to compete for the $500,000 U.S. grand prize. The group might consist of some previous champions as well.

CBS also revealed the first twist. For the first time ever, viewers will help choose who will participate in the game from among a pool of 20 of their favorite former houseguests from all six seasons.

When contacted by Jam! Showbiz about who the 20 would be and when fans would be able to start voting, CBS stated they are keeping that a secret for now.

As they say, stay tuned, folks.
