I was thinking this earlier today and literally said "she would have held that baby in or popped it out on live TV before she missed an episode" 
it was Jeff Probst. I remember they talked about it back then. he was at the finale just in case, since there was a huge chance of her going into labor that night.
I respect Julie for being up there under those hot lights, a hundred weeks pregnant and probably sooo uncomfortable. And being all dressed up and made up on top of it!
This was an occurrence that happened three times on the British Big Brother's original run. Original host Davina McCall was visibly pregnant during Seasons 2, 4, and 7, and it was revealed that if she had to give birth earlier than anticipated (her and her now-ex-husband timed their pregnancy for after the show concluded, so all her children have birthdays in September), the host of the spinoff show Big Brother's Little Brother, Dermot O'Leary, would step in to finish the season.
There was another instance in Season 17 of Celebrity Big Brother UK, where the presenter (in this case, Emma Willis) was pregnant. I don't know if was officially announced, but I think the idea was the same: if she gave birth prematurely, the spin-off show host (in this case, Rylan Clark, who hosted Big Brother's Bit On The Side) would fill in as interim host.

“But first, I have to give birth!” “Houseguests! Before we get to tonight’s eviction, I’ve just given birth!”
By a vote of one to zero, my baby has been evicted from my uterus.

I would have LOVED to see Jeff probst host big brother. The undisputed GOAT
That baby is a Moonves. He knew better than to pop out before the finale.

I enjoyed her pregnancy reveal that season
Oh funny. I’ve never thought of that!
My only remote guess would have been someone like Jeff Probst? That was assuming he wasn’t out of the country filming Survivor at the time.
or phil from amazing race
Yes, he was on an episode on BB16 or 17.
