CBS is giving "Big Brother" fans more to love.

The network has decided to double the show's Tuesday, Sept. 15 season finale, expanding it from one hour to two, insiders close to the production confirm. The grande-sized "Brother" will air live from 9-11 p.m., with Julie Chen set to host.

Look for the two-hour "Brother" to mix all the traditional elements of the final show -- specifically, the crowning of a winner-- with an extended reunion segment featuring return appearances by ejected houseguests. There will, of course, be a studio audience.

CBS's decision to double down on "Brother" is no surprise given the show's stellar ratings this season. Despite being in its 11th season, the show is up 5 percent in overall viewers-- an almost unheard of growth for such a veteran show.

In years past, producers have had to cram a whole bunch of elements into a one-hour finale, leaving limited time for reunion elements and cast interviews.
