Kate Middleton Pregnant? Denmark Trip Sparks Rumor

Is Kate Middleton pregnant? The Duchess has ignited speculation that she is expecting once again after a visit to a UNICEF distribution center in Copenhagen, Denmark.

With Prince William at her side, Kate avoided a certain food product as they sampled items from UNICEF aid packages sent to famine-stricken East African countries.

While members of the Danish royal family and William tasted peanut paste, Kate politely refused and reportedly gave her husband of six months a knowing look.

Doctors have frequently recommended pregnant women avoid peanuts and byproducts while expecting in order to help prevent allergies in their babies-to-be.

What's more, The Palace itself even "went out of their way to stress that she has no nut allergy whatsoever," an editor for Britain's The Sun told ABC News.

Whenever William and Kate Middleton welcome their first child, he or she will inherit the throne. The rules were changed to allow a first-born daughter to rule.

If they have a girl first, that is. The UK monarchy recently agreed that a first-born girl should be able to ascend the throne even if she has younger brothers.

Still, pregnancy speculation or not, Middleton is certainly not displaying any bump just yet; Britain's Best Dressed was slim and stylish as ever in Denmark.

Congratulations ... maybe!
