Marvin, 28, and Rochelle married last summer and announced the news they were expecting in November.
Rochelle tweeted: "I wanted to be the first to tell you...we have some exciting news to share!
"Marvin and I could NOT be more thrilled to announce that we are expecting our first child mid next year.
"We have always dreamt of being parents and the news is the best early Christmas present we could have asked for.
"I know Marvin is going to be a great dad and we're so excited to start a family.

"We are both at a great point in our lives and we are in a relationship in where we both feel comfortable to extend our love. It's Amazing, incredible and we can’t wait."
