The Princess Royal had guests in hysterics as she was tasked with cutting a cake during her latest royal outing.
Princess Anne, 73, celebrated the 35th anniversary of Wormwood Scrubs Pony Centre in west London on Thursday.
Her hosts presented the Princess with a chocolate and gold sponge cake to mark the milestone.
And in true Anne style, she prompted laughter from the crowd with a hilarious quip before cutting into the sweet treat.
See what she said in the clip below…
Anne also acknowledged words of support for King Charles following his cancer diagnosis and the Princess of Wales amid her recovery from abdominal surgery.
The Princess nodded and smiled as she was told, "We wish you and your family well at this time" by Sister Mary Joy Langdon, founder and chief executive of the Wormwood Scrubs Pony Centre.
