Model and Smirnoff spokesperson Amber Rose is pregnant, according to reports.

Rose, who is engaged to "Work Hard, Play Hard" rappper Wiz Khalifa, is due in January, Radar Online reported earlier this week.

"Amber and Wiz unexpectedly got pregnant, but they're really happy to be starting a family together. 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," a source told the gossip magazine.

The model famously dated rapper Kanye West, and then accused Kim Kardashian, his current girlfriend, of being a "homewrecker," sending West ray photos and texts while he was still with Rose. 

"She was sending pictures, and I was like, 'Kim, just stop. Don't be that person. I thought at least she'd be woman enough to respond to me.  She never responded. It's very important that us women stick together and we don't f**k each other over like that," Rose said in an interview with Star magazine.

But after her relationship with West ended, she was able to find true love with Khalifa.

"I want to thank her," Rose said about Kardashian. "Because if she was never a homewrecker, then I never would have met Wiz, and I wouldn't be as happy as I am now."The couple got engaged in April, and this will be their first child.
