Keshia Knight Pulliam's husband, Ed Hartwell, has filed for divorce after only seven months of marriage. Keshia, who is best known for playing young Rudy Huxtable on "The Cosby Show," is also currently expecting the couple's first child, or is she? According to reports, Ed Hartwell not only wants to end his marriage to Keshia Knight Pulliam, but he is also demanding a paternity test on her unborn child. 

Is the baby Ed's?

Ed, a former NFL player, filed papers in Fulton County Georgia on Monday citing irreconcilable differences as the reason for the divorce.  Of course, fans were shocked by the news, as Ed and Keshia haven't even been married for a whole year! To make matters worse, Pulliam is early on in her pregnancy and is due in January 2017. 

Ed Hartwell's rep revealed that he simply wanted to be single again and that he plans to file for a paternity test of the unborn child, which is said to be a little girl.

This sparks rumors that Keshia Knight Pulliam may have cheated on her husband, or he at least believes she could have.

Hartwell said to be very impulsive may have rushed into marriage.

Hartwell, who was formerly married to reality star Lisa Wu, is said to be very impulsive, and may have rushed into his relationship and marriage with Pulliam too fast. The couple had a surprise wedding on New Years Day after only dating for a few months.  Sadly, it seems that Keshia had no idea Ed was going to file for divorce. Earlier in the day, she posted a selfie on Instagram after a trip to the hair salon. 

The divorce could get ugly.

Although the couple has only been married for seven months, it seems that this divorce could get ugly. Keshia is bound to be more emotional due to her pregnancy, and when the baby comes along it will make the split even messier.

There will need to be a paternity test done, and if the baby is proven to be Ed's a custody agreement will have to be made. This could make for even more legal battles between the two.

It should be interesting to see how this celebrity split plays out in the months that follow the divorce filing and leading up to the birth of Keshia Knight Pulliam's baby girl.
