• Special family news for Princess Beatrice
  • Her daughter Sienna was christened
  • The royals had a private ceremony on Friday

Princess Beatrice and Edoardo Mapelli Mozzi's baby girl was christened over the weekend. The family had a ceremony for their daughter, Sienna Elizabeth Mapelli Mozzi, in London. Here are the details, plus which royals attended.

Royal christening for Princess Beatrice's baby Sienna

Sienna, who is 7 months old, was christened on Friday at Chapel Royal in St. James's Palace, according to Hello! It was a private ceremony, so the full guest list isn't known, nor are there any photos.

It's thought that Queen Elizabeth II, the baby's great-grandmother, was unable to attend. The Queen has rarely left Windsor Castle in recent months and hosted virtual appointments on the day of the christening.

But Princess Beatrice's parents were both there: Sarah Ferguson attended and Prince Andrew broke cover for the ceremony, as seen in photos by the Daily Mail.

Baby Sienna was born last year on Sept. 18. She'll be 8 months old in a few weeks, and her christening follows that of Princess Eugenie's and Zara Tindall's children. The two royals had a joint ceremony, attended by the Queen, in November.

Princess Beatrice and husband Edoardo Mapelli Mozzi have yet to share a first photo of their daughter.

The royal baby, who stands 11th in line to the throne, made them a family four — Edoardo has a son, Wolfie, from an earlier relationship.
