*Radaronline.com is reporting that Kim Zolciak of Bravo’s “The Real Housewives of Atlanta” is engaged to Atlanta Falcons star Kroy Biermann, the father of her unborn child.

“They wanted to announce it in a national magazine, but Kim was so excited that she told a couple of close friends about it,” a source told the website. “Obviously, they are both really happy about both the baby and their engagement and cannot wait to start their new lives together.”

The source added that Kroy, 25, bought Kim, 32, a “substantial” ring she has yet to wear in public.

Last week Kim confirmed to Life & Style that she and Kroy are expecting their first child together–and discussed her feelings about being a pregnant bride.

“I definitely don’t want to get married while I’m pregnant,” she said. “But I can see myself marrying Kroy in the future.”

In headlines yesterday, Kim was snapped smoking a cigarette while watching an NFL game when she was about three months pregnant.

In other Kim news, the reality star has put her townhome in Duluth, Georgia on the market for $499,000, according to Real Estalker.

She reportedly purchased the three story townhome in 2006 for $486,000. The property includes 3 bedrooms, 3 bathrooms and has over 3,396 square feet of living space.
