Kate Middleton returned to her royal duties on Thursday! The stunning brunette, who gave birth to her second child, daughter Charlotte, in May, visited a children's mental health center in London on Sept. 17. Kate showed off her new bangs and looked gorgeous in a black-and-white dress with black heels. The mom of two was all smiles as she mingled with people and press at the event. Kate's outing comes at the end of a busy Summer for the royal family. After welcoming Charlotte in May, Kate, Prince William, and their son, Prince George, attended the annual Trooping the Colour ceremony in London.
