Not only did we get a long-awaited glimpse of the precious six-month-old twins, but the couple also launched DemBabies.com, a site filled with never-before-seen photos of the famous family.
While the photos on their family blog paint a picture-perfect fairytale, Mariah says the entire journey has not all been easy. Before becoming pregnant with Roc and Roe, Mariah suffered a painful miscarriage. When she got pregnant again with the twins, it was an extremely rough period, filled with emergency trips to the hospital and days where Mariah could not even get out of bed.

"I was so miserable," said Carey. "I don't think I understood the enormity and the magnitude of what it really does to your body. I had serious back pain. It was a huge strain."
Despite the hardships of her pregnancy, it's clear to see that the Cannon family has blossomed and is enjoying every moment of their new lives as parents. Mariah and Nick are so in-sync that at one point during the interview, they were finishing each other's sentences!
"My family gives me everything. My family means the world to me," said Cannon. "It's completion."
