"Amber and Wiz unexpectedly got pregnant, but they're really happy to be starting a family together," a source close to the situation told RadarOnline.com.
"Amber's already had to make some big lifestyle changes, like not smoking cigarettes anymore. As a model she's used to having a thin waist, so this is going to be an adjustment for her."
Wiz and Amber revealed their engagement in April when the rapper gave her an enormous oval-shaped diamond ring.
This will be the first child for both.
