Lookin’ good, Kate! Duchess Kate rang in her 34th birthday on Saturday, January 9, in typical fashion — nothing extravagant, just something simple.

A rep for the royal tells Us that she and her husband, Prince William, will celebrate the day “privately.”

“It will be a low-key celebration,” a source tells Us. “Kate doesn’t like to make a fuss.”

William will turn 34 in June.

It’s been a busy year for the Duchess of Cambridge, who gave birth to her second child, Princess Charlotte, last May. (The royals are also parents of Prince George, 3.)

In October, the couple revisited the University of St. Andrews in Fife, Scotland, where they first met and fell in love 12 years ago, and later joined Prince Harry to support the Scottish Mental Health Arts and Film Festival.

The pair is also set to embark on a tour this spring — sans kids — visiting India and Bhutan together for the first time. They may even re-create the late Princess Diana’s famous 1992 photo at the Taj Mahal.

“TRHs look forward to following in the footsteps of previous generations of their family with their upcoming tours,” the official Twitter account for Kensington Palace tweeted on Friday, January 8, alongside image of Princess Diana, Prince Charles and the queen.
