Prince Harry and his girlfriend, Cressida Bonas, got cozy at the We Day UK charity event at Wembley Arena on Thursday. Earlier this week, the pair had a dinner date, but the couple's We Day UK outing marked the first time Cressida joined him for an official royal appearance. On the red carpet, Cressida posed for pictures wearing sequined Converse alongside her half sister, Isabella Calthorpe, and Isabella's husband, Sam Branson. Inside, Cressida and Prince Harry sat with a big group of friends and family, which included Prince Harry's cousin Princess Beatrice. During the event, Prince Harry took the stage to speak in front of more than 12,000 students, joking, "For those of you who were expecting Harry Styles here, I apologize, and no, I am not going to sing." He also admitted to feeling nervous on stage before adding, "Some people do not think it is cool to help others.
