Julie Chen has been "but first"-ing it on Big Brother for 15 years (and 17 seasons!) as "The Chenbot," and says she's finally learned to embrace her on-air persona.

"Well, the truth is, I've always thought it's funny behind the scenes when I talk to friends and family," Chen says of being called Chenbot. "And now I'm letting in the people who watch the show ... I like it because they get a kick out of it."

Chen credits her five years on The Talk with helping her break out of her on-air shell on Big Brother. "I always just saw myself as the question-asker," Chen said. "I also saw myself as just, like, 'I'm the voice of Big Brother. These houseguests should be a little bit scared of me. And when I come on the screen, they should do as I say and answer my questions, and then that's it.'... [Now] I like showing that I have a sense of humor about myself."

Still, the Chenbot front has come in handy over the years -- helping Chen hide her reactions to the show's shocking events on-air. Naturally, ETonline had to ask Chen to name Big Brother's most shocking moment ever.

"We've had a lot of shocking moments," Chen said. "Look, season three when Marcellas [Reynolds] had such arrogance and didn't use the 'Power of Veto' to save himself? That was a window into human nature ... he got evicted moments later. That's one of the biggest shocks."

Chen also revealed her least favorite Big Brother show moment ever. "In season four, when Jun [Song] won the game and everyone else was so bitter?" Chen said. "I'm like, 'You're crushing the moment!' You know? Like, what a mood killer!"

Speaking of Big Brother winners, Chen revealed her plan to bring all 17 back to the house: All Stars 2! Fans have been begging for another "All Stars" season since the first edition aired in 2006.

"I have been actually pushing for an All Star season in that it's beyond 'all star,'" Chen teased. 'It's the cream of the crop. It's the winner from each season to compete. So, it's the 'Winner's Circle.' And I'm talking back to season one, Eddie [McGee]. I mean all the way back!"
