Keshia Knight Pulliam and husband Ed Hartwell are headed for divorce.

News outlets reported Hartwell filed to end his marriage to the 37-year-old actress Monday in Atlanta, just a week after Pulliam announced she's expecting her first child.

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.

Hartwell's rep made a statement to the website that suggested the 38-year-old former NFL player is questioning the baby's paternity.

"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.
