Amber Rose Pregnant--No Stretch Marks at Nine Months

Model Amber Rose is nine months pregnant with her rapper fiancé Wiz Khalifa's baby.

And the 29-year-old socialite was bragging all about her smooth, stretch mark-free body on social media outlets. Rose posted a photo of herself, only wearing a bra and underwear, via Instagram on Jan. 27.

"Nine months pregnant and no stretch marks on my body, Thank you Jesus!" she posted.

And her smooth skin at nine months is not the only thing the model is bragging about.

"I'm so ready. I'm going all-natural. I've decided that I'm going to have an all-natural water birth. No medicine," Rose said in an interview with XXL magazine. "I want those bragging rights! The next time Wiz has a stomachache or anything, I'll say, 'I popped out a baby all-natural.' "

Rose and Khalifa revealed that they chose a "total boss name" for their child-to-be in an interview with Big Boy on LA radio station Power 106. The couple also said that "It's a normal name, but it's not common."

"We've had the name for a long time," Rose said.

Khalifa added that he plans to spend more time at home to be of more assistance to Rose while she is going through her pregnancy.

"I'm at home full-time," he said. "I'm just working on videos for O.N.I.F.C., bringing that to life. I'm really staying around because this is an important time for Amber. She really needs that support."

Rose also posted pictures of herself participating in a prenatal yoga class.

"Prenatal Yoga- One of the positions that got me here in the first place Lol ;-)," she joked on Twitter.
