Even with so much to celebrate, the Duchess of Cambridge is unlikely to be partying into the night or toasting her 31st birthday with glasses of bubbly.
Pregnant Kate, 31 on Wednesday, and entering her second trimester, is said to be keeping a low profile and spending her special day “privately,” according to her office.
Some reports suggest they are at their rented home in North Wales – a perfect secluded place for a quiet walk in the winter sunshine and fresh air with their cocker spaniel Lupo.
