Duchess Kate's High Heel Stuck in a Drain Grate: PHOTOS

Duchess Catherine aka Kate Middleton nearly fell during the St. Patrick's Day military parade at the Aldershot Barracks Sunday when her stiletto heel got stuck in a drain grate.

Her Royal Highness, 31, was dressed in a green Emilia Wickstead dress coat that she has previously worn prior to her pregnancy.  She paired it with a stylist black hat and Emmy pumps that she accessorized with the Queen Mother's gold shamrock brooch.

Prince William, the Duke of Cambridge, held his pregnant wife's hand and smiled as she bent down to pry her shoe out of the grate and put it back on her foot.

The couple are expecting their first child in July and have been decidedly guarded when asked about the gender of their unborn child.

One military man was guilty of a kiss and tell conversation he shared earlier today with the mother-to-be.

Guardsman Lee Wheeler asked Kate about the couple's individual preferences.  He revealed, "I was talking to her about the baby, of course.  I asked her, 'Do you know if it's a girl or boy?', and she said, 'Not yet.'  She said, 'I'd like to have a boy and William would like a girl'.  That's always the way."
