"It's crazy. You would think we all like got together one night and discussed this master plan," the 32-year-old MTV star quipped. "It's been really awesome."
"It's cool to be working with someone and also have that support too," the mom-to-be continued. "You have your good days, your bad days and they really know what you're going through."
She also added that The Hills stars Kristin Cavallari and Audrina Patridge are already moms. "The five main Hills girls are all married or pregnant or moms," she noted. "Being a mom is the best thing in the world, so I'm really excited for them."
In a recent interview with ET, Cavallari gushed over Conrad's pregnancy, saying, "I'm so happy for her, and it's cool to see the evolution of everybody from The Hills and Laguna Beach and to see how everyone is growing up. It's been really fun to watch!"
