"Being able to bring a life into the world is every woman's dream but for me it's more than just a dream it is a magical, mystical journey which I get to share with this amazing man," Marcille told BET. "Kevin is the only man who I would share this moment in life with."
Marcille is reportedly five months pregnant with her first child.
After winning the third season of America's Next Top Model back in 2005, Marcille went on to host My Model Looks Better Than Your Model and Rip the Runway on BET. She's also taken advantage of a few acting gigs over the years.
"My life continues to be a bundle of incredible experiences," Marcille added. "I get to do this incredible show on BET and I get to be a mom and live this amazing life that God has bestowed upon me. Who could ask for anything more?"
Marcille's relationship with McCall, 28, went public last March.
