The young princess was seen staring innocently at the floor as her mother greeted Reverand.
The Duke of Cambridge and Prince George seemed more engaged when greeting.
However, the princess still steals the show and has been much appreciated by Twitter users who praised her good looks.
Patricia Hogson said: “Charlotte has the Queen’s beautiful cheeks and smile…beautiful children, very well dressed…love traditional clothes.”
Her appearance at the Easter service is Charlotte’s second public appearance in three weeks after winning the hearts of royal fans at a memorial service dedicated to her late grandfather, Prince Philip.
Today the princess was seen wearing a floral spring dress with an elegant cardigan as she walked towards the service.
Older brother George emulated his father by wearing a navy suit.
The Duchess of Cambridge matched her daughter’s colors by wearing a light blue coat with a darker shaded hat.
The Queen, who has had problems with mobility, does not attend the service, which is a staple of the royal calendar.
The Prince of Wales and the Duchess of Cornwall, who represented the Queen at the King’s Royal Mass on Thursday in the same chapel, did not attend Easter Mass.
