Kim Zolciak pregnant and ghost hunting!

"Real Housewives of Atlanta" star Kim Zolciak and her boyfriend, NFL player Kroy Biermann, are expecting their first child together reports Life & Style. "I was surprised!" Zolciak says. "While it wasn't planned, God clearly has a bigger and better plan for us and we're excited."

Zolciak previously denied reports that she was pregnant when an angry ex leaked the information to the media. "I was appalled and disgusted by that," she says. "I wasn't through my first trimester -- you never know what could happen."

While she has no plans to marry during her pregnancy, the "Google Me" singer says, "I can see myself marrying Kroy in the future." Kim has two daughters from a previous marriage, Brielle, 13, and Ariana, 9.

In addition to taking on motherhood, Zolciak, along with co-stars Sheree Whitfield and NeNe Leakes, will be taking on ghosts when they drop by the Dec. 1 episode of "Ghost Hunters." The trio will "roll up their sleeves and put their burgeoning careers and sass aside in order to help Jason and Grant conduct another spine tingling investigation at Rhodes Hall in Atlanta, GA."
