"We are so excited to start our family together and our hearts are exploding with love for our baby boy," she said.

Becoming a mom has been in Paris' plans for a long while now and she's spoken before about her "struggle" to start a family.

"It's always been my dream to be a mother, and I'm so happy that Carter and I found each other," Paris told People.
