Kate Middleton and Prince William kept with tradition on Saturday. Kate wore a festive green coat and shamrocks at a St. Patrick's Day celebration. Her baby bump also made a special appearance. The royals visited the 1st Battalion of the Guards regiment in Hounslow, London. The Duke and Duchess also petted the guards' mascot, a grand Irish wolfhound.
The couple's third child is due in April, so she skipped drinking the annual pint of Guinness.
