Duchess Catherine showed off her baby bump under her green overcoat as the royal couple visited with the Irish Guard.

Prince William and Duchess Catherine, aka Kate Middleton, have almost broken the internet this St. Patrick’s Day as they charmed during their St. Patrick’s Day trip to honor the Irish Guards, and of course their Irish Wolfhound, Domhnall.

The royal couple were visiting with the 1st Battalion of the Guards regiment at their barracks in Hounslow, west London. Three-hundred-and-fifty troops led by mascot, Irish Wolfhound Domhnall, marched out for the couple. Kate handed sprigs of shamrock to officers and warrant officers.

The longest-serving Guardsman in the Battalion then led a toast to the couple. Prince William enjoyed a pint of Guinness while Kate, who’s eight-month baby bump was showing under her green overcoat, drank a glass of water. She also enjoyed meeting the troop’s mascot, the Irish wolfhound, Domhnall.

The Duchess wore a forest green wool coat, with black trim, and matching hat. She accessorized with drop earrings, black gloves and winter weather-friendly black tights, and suede pumps.
