Amber Rose is reportedly pregnant with Wiz Khalifa's first child.

"Amber and Wiz unexpectedly got pregnant, but they're really happy to be starting a family together," says a source close to the couple. "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."

The pair were engaged in April, but may move their wedding date up to October to accommodate Rose's expected delivery in January. That would presumably give the couple more time to prepare and whatnot. Regardless, congratulations to them.
