During her in-depth special with Giuliana Rancic, the former Laguna Beach star revealed that Cutler was all up in the mix when their baby boy was about to enter the world.
And that's not what she had anticipated.
"I was like, ‘You're gonna be behind me, you're not gonna see anything,'" she told Giuliana.
"And the nurse was like, ‘Oh, no, no, he's gonna hold your leg.' I was like, ‘Oh, no he's not!' She's like, ‘It's different when it's your own.' Well, at that point I'm like whatever. So he held my leg, he saw the whole thing."
