Kate Middleton and Prince William made their annual appearance at the 2018 St. Patrick's Day Parade in the UK on Saturday to honor the Irish Guards. Kate, who is expected to give birth to their third child next month, looked regal in a festive green coat trimmed with black fur cuffs and a black fur collar. Prince William looked equally dapper in his traditional ensemble as well. During their visit, Kate and William got in on the celebrations with a pint of Guinness for William and a glass of water for Kate, of course. Kate also petted the regimental wolfhound mascot outside while flaunting her growing baby bump.
