Keshia Knight Pulliam and husband Ed Hartwell are headed for divorce.
Hartwell cited irreconcilable differences, "such as constant disagreements on life changing decisions that couples typically make together," for the split, according to The YBF.
Court documents reveal Pulliam is contesting the divorce petition.
Sources told The YBF on Monday that Pulliam wasn't aware her husband had filed for divorce.
"Right now, the only thing I want is a paternity test for the baby," the spokesperson said on Hartwell's behalf.
Pulliam and Hartwell married in January after four months of dating.
"I am expecting my first baby and I am so excited!" she said. "She is so spoiled already!"
Pulliam is best known for playing Rudy Huxtable on the NBC sitcom "The Cosby Show." She later appeared on Tyler Perry's House of Payne and competed on "The Celebrity Apprentice" Season 7.
