Demi Moore has Emma Heming's back amid ex-husband Bruce Willis' battle with frontotemporal dementia. Last week, the former model revealed to Diane Sawyer for the ABC News special, Emma and Bruce Willis: The Unexpected Journey, that she made the difficult decision to have the 70-year-old actor live separately from her and their two daughters, 13-year-old Mabel and 11-year-old Evelyn. Emma explained that she thought it was not only best for Bruce to receive around-the-clock care, but also for the girls, noting that this was what he would've wanted for them.
