Scar on his lip is not result of plastic surgery or anything like that. He was born with it. "The scar on Phoenix's lip is popularly believed to be the result of a repaired cleft lip. However, he has stated in interviews that his mother, while pregnant with him, felt a sharp pain one day and he was born with a scar on his lip. The birth scar is a microform, almost taking the form of a cleft, as the tissues just reached far enough to join up; since the bone and muscle tissues joined correctly no surgery or cleft repair was required."
