She might only be three months along in her pregnancy, but it looks like Jill Duggar and her husband Derick Dillard already know the sex of their baby. It's being reported that the couple might have spilled the beans with certain items they've added on to their baby registry this past week.

According to The Stir on Tuesday, Duggar and Dillard have dropped some pretty big hits about the sex of their child. The new parents are requesting a three-piece crib bedding set in a 'Tea Party' print, a mini couture tuxedo bib and bibs and pacifiers representing the Arkansas Razorbacks and the Oklahoma State Cowboys. The site says that these items suggest that the couple may indeed be expecting a baby boy.

So far, Duggar and Dillard haven't commented on the rumors, but they did reveal that their due date for 'Baby Dilly' is on March 24, 2015.

Meanwhile, Duggar has revealed that she was rather surprised to find out about her pregnancy.

The reality television star, who wed husband Dillard earlier this summer, said that she took multiple pregnancy tests before realizing that she was indeed expecting her first child.

According to Us Weekly last Tuesday, she said, "We were really surprised when we got that positive test but of course we were really excited. I think we would have even been less surprised had it come back positive on one of the first tests."

Duggar also reveals that there was a little confusion after the couple saw their first test before realizing what the result was.

"One of the [previous] pregnancy tests had the little plus sign and the other one had the straight line," Duggar explained. "The one we had taken two days before was the one that was supposed to have the plus sign. The one I took at my mom's was just one line."
