She admitted that it is helpful to hear about her fiance's ex and their experiences parenting together. However, that does not make it any less challenging.
The American Idol judge explained, "So, as much as I was a little bit like, 'I don't need to hear all those stories,' they actually helped. They're like, 'Oh, you've had a run at this. You know how to do this.'"
She also gushed about her relationship with Bloom. "He's been amazing, incredible, and we're so in love and we're so grateful," Perry said.
He helped her through the birthing process as well. The singer explained, "He was such a great support. We had, like, a little boombox. He was there, and he was so wonderful and just holding my hands and looking into my eyes."
