Just because she's due to give birth in the next few weeks, doesn't mean Kate Middleton is slowing down!

On Tuesday, March 17, the Duchess of Cambridge --who's expecting her second child in April -- handed out shamrocks to soldiers from the 1st Batalion Irish Guards at Mons Barracks in Aldershot to mark St. Patrick's Day.

For the special occasion, the 33-year-old mum wore a dark Catherine Walker coat, black pumps and a Lock & Co. hat that revealed her twisted updo.

The Duchess let her "accessories" speak for themselves. Wearing a sprig of shamrocks and a gold shamrock brooch given to the Queen Mother by the Irish guards, Catherine looked every inch the royal, and definitely would have made the Queen Mum proud.

According to the Mirror, Kate was following a century-old tradition that began in 1901 by Edward VII's wife, Queen Alexandra, whereby a senior female member of the Royal Family presents shamrocks.

Hubby Prince William was also on hand, looking dashing in full military regalia.

The twosome are eagerly awaiting the arrival of a new little prince or princess, which is why Catherine has been stepping up her public appearances before she goes on maternity leave.

Last week, Duchess Kate attended a service honouring those who lost their lives fighting the war in Afghanistan and visited the set of "Downton Abbey," where she got to meet Lady Mary, Mr. Bates, Mrs. Patmore and Mr. Carson among others.

It won't be long now until we see her and Will's bundle of joy!
