*Oooh, that had to be embarrassing.

Former Television talk show host and magazine editor, Star Jones was put on blast when she was served with court papers at her book signing at Bookhampton in East Hampton on Saturday by none other than her ex-husband Al Reynolds.

According to reports, the  “Celebrity Apprentice” star was obviously perturbed and quite horrified after the processor served the papers and snapped a picture.

Sources say Reynolds had been having difficulty serving Star since he filed a lawsuit against her in May for allegedly breaking a divorce agreement because she was traveling around the country promoting her book, “Satan’s Sisters.”

The pair signed an agreement in their 2008 divorce not to make “disparaging remarks” about each other in the media. So now her ex is asking for $50,000 in damages for Jones allegedly breaking their contract.

Reynolds claims because Jones called their marriage, “king of booty” on the Wendy Williams show on March 28, she’s in violation.
