Mike Tindall shared details of his son, Lucas' joint christening on Sunday with Princess Eugenie and Jack Brooksbanks' little one, August.
Young Lucas even enjoyed having holy water from the River Jordan poured over his head.
Queen Elizabeth also attended the joint christening at Royal Chapel of All Saints in Windsor despite recent health setbacks, which resulted in her cancelling numerous engagements.
The queen seems to be back at work. Though she would've marked her 74th wedding anniversary with Prince Philip, who died earlier this year, on Saturday, Wednesday saw her meet in person with Mr Andrew Bailey, Governor of the Bank of England, for an Audience at Windsor Castle.
As Head of State, Her Majesty regularly meets notable diplomatic, religious, military and political figures.
