Sure, we know that child stars have to grow up sometime and they’ll go from cherub-cheeked angels into adults. But some of the celebrities we first encountered as adults have still managed to turn into people we do not recognize any longer. We will show you 10 truly shocking celebrity transformations. Renee Zellweger has a very distinctive looking face, but one we haven’t seen in awhile since her infamous red carpet appearance. She denies any allegations of plastic surgery, but some claim that to be the only explanation for the sudden change. Courteney Cox and Matthew Perry played husband and wife on the hit show Friends, but they have also undergone startling and sudden changes in their appearances since then. Tara Reid admits to having some procedures done, but claims that her dramatic weight loss is just how she is and not as a result of plastic surgery or illness.
