Dan Gheesling -- who won season 10 and was the runner-up on season 14 of "Big Brother" -- says if Julie steps away from her hosting role on CBS' hit reality series, whoever replaces her will have some massive shoes to fill. Her 18-year run has been that iconic.
So far, Julie has not given even a hint that she'll leave the show. In fact, she made it clear... she'll be hosting Thursday night's episode.
The real question ... will "Big Brother" go on the chopping block now that Moonves is gone? Sharon Osbourne said this week on "The Talk" nobody's job is safe now ... nor are any of the CBS shows in the wake of Moonves' departure.
Ultimately it comes down to ratings. Although Dan says the show is a juggernaut ... the ratings are down this season from last, although the all-important demos are still strong.
As they say in TV land -- TBD.
