Proud mum Sharon Osbourne has hailed her hero son as "Super Jack" for bravely tackling a mugger who snatched a woman's handbag. The former X Factor judge heaped praise on Jack when she appeared on 'Access Hollywood': 

"He was having coffee in London outside a little cafe when the lady at the next table screamed. Somebody grabbed the bag off her. This guy is running down the street so Jack - Super Jack - comes running after him and tackled the guy, got him down on the ground and then called the cops."
