Melissa Joan Hart says her family has always "leaned in" to their faith - but 16-year-old son Brady's decision to dedicate his life to Christ was a welcomed holiday surprise. "[My kids] were all baptized as babies, because I was raised Catholic and my husband was raised Baptist. We kind of raised them Presbyterian, but we're back in a Baptist church now and Brady just felt very called," Hart, 49, exclusively told Us Weekly while discussing her charity work with World Vision.
