Demi Lovato is reflecting on her life after her near-fatal overdose in her first major interview since her relapse. The "Sorry Not Sorry" singer spoke at the Teen Vogue Summit in Los Angeles on Saturday and said she's stronger than ever. “What I see in the mirror [is] someone that’s overcome a lot. I’ve been through a lot and I genuinely see a fighter,” the 27-year-old star told Teen Vogue's editor in chief Lindsay Peoples Wagner. "I don’t see a championship winner, but I see a fighter and someone who is going to continue to fight no matter what is thrown in their way," Demi Lovato added.
