However, royal fans expecting to see Kate to mark the occasion with a lavish birthday party will be disappointed.
The Duchess of Cambridge’s birthday celebrations are expected to be a low-key and private affair. That is in contrast to press reports which say she will hark back to her youth with an 80s themed party.
As Kate turns 30, a more casual party seems appropriate for the woman who along with her husband, Prince William, has been given the responsibility for modernizing the British monarchy.
Looking back over the months since her wedding, it is widely acknowledged that Princess Catherine has done pretty well. She and Prince William appear to be a good team and genuinely in love as a couple.
The past year has seen momentous changes for Kate, with a fairytale wedding to Prince William, travels around the world and glamorous appearances that marked her transition from commoner to the world’s most talked-about princess and style icon. She has won rave reviews for her sparkle, her elegant sense of style, and her friendliness with the public.
On Sunday, they were out in force with the duchess again the center of attention as she and William took to the red carpet for the premiere of Steven Spielberg’s movie War Horse in central London.
Now, Catherine is expected to settle quietly into life as a British royal. It will be a busy year as Queen Elizabeth II is celebrating her Diamond Jubilee. The royals are expected to play a supporting role by traveling overseas to represent the queen. William and Kate are due to journey to Malaysia, Singapore, the Solomon Islands and the tiny Pacific island of Tuvalu as part of the festivities.
The former Kate Middleton will have to carry out her duties without upstaging the monarch in her moment of glory, and also playing a supporting role at the London 2012 Olympic Games.
This week, royal officials announced which charities she is supporting, including the Scouts and a group that helps drug addicts. More organizations will follow later, officials said. She has already taken on an unofficial role as a champion of the British fashion industry, wearing the creations of British designers at home and abroad, showcasing their work in the best possible light.
Of course, a major role expected of Princess Kate in the near future is as the mother of the future King or Queen; their first baby will be the third in line to the British throne regardless of sex, as the ancient tradition of primogenitor has been overturned.
