Congrats to Wiz Khalifa and his fiance Amber Rose. The couple is expecting their first child!

Via Radar Online:

Amber Rose and her fiancé Wiz Khalifa are expecting their first child together and RadarOnline.com has exclusive details about the model’s pregnancy.

“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.”

Hip hop gossip website MediaTakeout was the first to reveal Amber’s pregnancy on Monday, noting that she’s due in January and the couple may push their wedding date up to October.

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.
