Princess Kate Middleton held hands with school children and rode on a school bus during a visit to London’s National Portrait Gallery

Kate Middleton bonded with a group of young children for a fun art project at the National Portrait Gallery in London on Tuesday, Feb. 4

Kate, the Princess of Wales, went back to school Tuesday, joining a group of young students on a field trip. The 43-year-old princess, a mother of three herself, surprised visitors outside the National Portrait Gallery in London when she stepped off a bus with a group of 4 and 5-year-old students from All Souls CE Primary School.

Kate Middleton made an official visit to the National Portrait Gallery today and arrived in a different kind of style. Instead of the usual convoy of royal vehicles, the Princess instead emerged from a bus alongside school children as they excitedly made their way to view a new project in the gallery.
