Disney star Bella Thorne took time out of her busy schedule this week (begs24Jun13) to visit a group of youngsters at an orphanage in South Africa. The 15-year-old singer/actress is in the country shooting upcoming movie Blended and she used a day off from filming to meet children at Sparrow Village, a centre for kids who have lost their parents and a hospice for those suffering with HIV/AIDS. Thorne was overwhelmed by the visit and took to her Twitter.com page to tell fans about the trip. In a post, she writes, "These children are my life. I can't even begin 2 (to) describe the pure joy that comes from their hearts."
