Except when you get to Michael Jackson amounts of surgery I have never been good at telling if someone has had something done or not. A lot of times sleep and exercise could make the below changes.
I don't think so. in one picture he has his eyebrows raised, making his forehead "crinkle". also keep in mind if the January photo is a TV related gig, he will have makeup on. I do not see somebody as old as him seeking plastic surgery to enhance his image....he would start on those choppers first. BUT....he has been doing coloring to his hair i noticed....
He's also smiling in two of the three pictures while looking "plain" in the other one. Smiling does stretch the skin... However, my horse Hodson is jealous of the teeth...
