The holidays are a time for goodwill and cheer, which is why Katy Perry and her boyfriend Orlando Bloom visited the Children's Hospital Los Angeles. The pair dressed up as Santa Claus and his wife, Mrs. Claus, and walked around the hospital taking photos, handing out gifts, and joining a holiday sing-along. The hospital posted 20 photos of the two on their Facebook page. Both Orlando Bloom and Katy Perry are recognized UNICEF Goodwill Ambassadors.
