'Big Brother' all-star competition planned

LOS ANGELES, April 13 (UPI) -- The CBS reality show, "Big Brother," will return this summer as an "all-star" competition featuring contestants from past shows, it was reported Thursday.

This time around, viewers will choose the 20 contestants, marking the first time the public will be involved in the casting, the New York Post reported.

A $500,000 prize will be at stake during "Big Brother: All Stars," which does not yet have a start date, CBS said.

The network said "Early Show" co-host Julie Chen will return to host the latest "Big Brother."
