On Tuesday, US Weekly reported that Kate Middleton attended the annual St. Patrick's Day parade that was hosted in Aldershot, England.

Though she didn't show up in a green coat, she accessorized with a golden, shamrock-shaped brooch which once belonged to the Queen Mother.

It's rumored that this was the last public engagement for the Duchess of Cambridge before she gives birth to her second royal child.

Hello Magazine previously reported that the Duchess picked this event as one of her final royal engagements.

The princess was set to attend the St. Patrick's Day Parade at Mons Barracks on March 17th and was accompanied by her husband, Prince William.

Middleton handed out shamrocks to guardsmen as she has done in the past. This is a tradition started in 1902 by Queen Alexandra, the wife of Edward VII.

The expectant mother was also spotted talking to a group of young girls and smiling.

As has been done in the past, the guardsmen in the battlion toasted to the royal couple and thanked them for coming.

Though she seems to be keeping pretty busy for someone who is in her final weeks of pregnancy, there has been some speculation that Middleton hasn't had enough royal duties.

Daily Mail reported that the Duchess of Cambridge has carried out only 76 total public engagements in the last year. That may sound like a lot, but compared to 93-year-old Prince Phillip who went to 200 events, it definitely sounds miniscule.

The Queen herself, who is 88-years-old, attended the most with 375. Middleton's total is barely a fifth of the number attended by the Queen who would sometimes attend six or more each day. Out of the 15 royals, Middleton performed the fewest public duties.
