Some major life changes are on the way for Amber Rose and Wiz Khalifa.

About six months after the couple announced its engagement, sources now confirm Rose is pregnant with her first child!

"Amber and Wiz unexpectedly got pregnant, but they're really happy to be starting a family together," a source close to the tandem tells Radar Online. "As a model she's used to having a thin waist, so this is going to be an adjustment for her."

It's true. She will also need to be responsible for the care and well-being of a tiny human being.

Rose famously dated Kanye West prior to Khalifa and is reportedly expecting to give birth in January. She and her fiance may move their wedding up to October as a result.

It will be the first child for both and we send Amber and Wiz our very best wishes.
