Julie Chen is co-host and moderator of "The Talk" and host of "Big Brother."
Chen and her "Talk" co-hosts -- Sara Gilbert, Sharon Osbourne, Holly Robinson Peete and Leah Remini -- moved into the "Big Brother" house to compete against each other for a special themed segment to be broadcast on "Talk" Thursday.
The segment was taped before the competition show's contestants arrived for the season, which premieres Thursday night.
"Inside the house, the ['Talk'] hosts spent an evening partaking in the full 'Big Brother' experience by playing an abbreviated version of the game," CBS said in a synopsis. "Together, they compete in a 'Head of Household' competition dressed as frogs, where one woman is crowned HOH; three ladies are then relegated to eat the infamous slop, two are nominated for eviction, and one is voted out. The ladies will reveal the host that was evicted on Thursday's 'The Talk,' which will also feature guest visits by past 'Big Brother' winners Dr. Will Kirby and Mike 'Boogie' Malin."
