Here is a photo of Ansel Elgort a.k.a. Augustus Waters a.k.a person who you cried tears for while watching "The Fault In Our Stars." It is a photo by him of a photo of him (and some poor individual who has no idea that he/she is on the same plane as Ansel Elgort).
Whether this counts as a "selfie" is up for debate, but life is short. There's no reason to make things too complex.
