Princess Charlène of Monaco (40) loves to share photos of her family on social media and is particularly fond of sharing adorable pictures of her twins, Prince Jaques (4) and Princess Gabriella (4) on Instagram. She posted a gorgeous New Year's photo taken in Lapland just a few weeks ago and also on the twins' fourth birthdays.

Now, Princess Charlène of Monaco is in New York with her twins and, naturally, the adventure just wouldn't be the same without photographic evidence! The royal blonde beauty shared a cute snapshot of her daughter and son visiting Ground Zero, where the twin towers of the World Trade Centre once stood.

Charlène also posted a video, with Jackson 5's catchy ABC in the background, of more of the twins' New York adventures with the caption, "First trip to NY. Great adventure and a wonderful experience! Thank You "
