Princess Kate: She missed this family celebration after being discharged from hospital. Princess Kate secretly left the clinic through the back exit.

Carole Middleton will be 69 years old on January 31st, and Princess Kate will be celebrating so soon after she was discharged from the hospital. Easter Sunday falls on March 31st in 2024 - so Princess Kate would have around two months to fully recover from her operation. However, this also means that Kate may not be fit enough to celebrate her mother's birthday.
