On a royal visit, Duchess Kate was stumped by a question from a London schoolgirl.

The question, does the Queen eat Pizza?

People magazine write that Kate Middleton had the best reaction,

"You Know, that's such a good question.  I don't know.  Maybe next time I see her shall I ask? The questions, does the Queen eat Pizza?  Kate's brilliant answer, "I am not sure, will ask her next time."

The schoolgirl responded with a lively "yes."

Yesterday's visit was for Kate to meet and discuss the benefits of urban gardens.  She walked around the allotment plots to see what the children had been growing and also took part in winter planting in a nearby greenhouse.
