A couple of weeks ago Wiz Khalifa shot down rumors that Amber Rose was pregnant
Insiders say Wiz was lying...

From Radar Online

"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."
