Wiz Khalifa and Amber Rose Expecting First Baby?

Rumors are swirling that Wiz Khalifa and his buxom fiancée Amber Rose are expecting their first child together.

A source told RadarOnline.com: "Amber and Wiz unexpectedly got pregnant, but they're really happy to be starting a family together."

The couple had been dating for a little over a year when Khalifa unexpectedly popped the question in bed this past spring. Soon after, Rose admitted that her soon-to-be hubby "wants 5 kids, so we better get on it, soon."

The rapper and model were planning on walking down the aisle this winter, and the baby rumors started popping up when news Rose was trying to push up the nuptials to October surfaced. Gossip site MediaTakeout brags that it has confirmation on the baby news.

This isn't the first baby rumor for the Taylor Gang boss and Rose. Earlier this month, Philadelphia's Hot 107.9FM put Wiz Khalifa on the spot, asking if Rose was pregnant with the couples first baby. Although Khalifa denied it, he did elaborate and say "she will have my baby in life, and you guys will know when she's pregnant." While both are avid tweeters, neither has taken to their Twitter account to confirm the news ... yet.
