The Princess Royal may have had a personal celebration on Thursday, but it was business as usual for the hard-working royal.
Princess Anne marked 32 years of marriage with her husband, Vice Admiral Sir Tim Laurence, on 12 December but the King's sister spent the day carrying out engagements in Norfolk and Suffolk.
Firstly, Princess visited Quadram Institute's Science, Food and Health Research Facility in Norfolk on Thursday morning.
Arriving wearing a chocolate brown coat, a patterned scarf and knee-high boots, she later donned a lab coat to tour the facility on the Norwich Research Park.
The Quadram Institute brings together researchers, academics and NHS clinicians to address global challenges in human health, food and disease.
Anne shook hands and met with 60 members of staff and students during her visit.
Her next port of call was a Beneficiaries Christmas Luncheon at Newmarket Racecourse, Rowley Mile, Newmarket. Anne, who is a former equestrian, attended the event in her capacity as President of Racing Welfare.
No doubt the Princess was back at her Gloucestershire estate in time to celebrate her wedding anniversary.
She and former Royal Navy officer Sir Tim tied the knot at Crathie Kirk church, near Balmoral, in 1992 as the Church of Scotland permitted second marriage for divorcees.

There were around 30 guests in attendance at the private ceremony, with the bride wearing a white knee-length dress with a spray of flowers in her hair.

Sir Tim often accompanies his wife at royal engagements and was knighted as a Knight Commander of the Royal Victorian Order by the late Queen in 2011.
