London: Former `Friends` star Jennifer Aniston has been told to have plastic surgery done on her legs by her good friend Demi Moore.
Aniston, 44, prides herself on staying in top shape and was said to be lapping up compliments about her sexy physique on the New York set of `Squirrels to the Nuts` ? until her longtime friend Moore called her, reported Showbizspy.
"Jennifer has always appreciated Demi because she does not hold back her opinions. But she wasn`t happy when Demi told her she needed her knees fixed. Demi even gave Jen the number of her plastic surgeon," a source said.
"Now, Jen`s seeing over photos of her knees, wondering if there is something wrong with them. She thinks they look pretty good, but there is one long wrinkle above both knees that she would like to address," the source added.
Aniston`s fiance, Justin Theroux, however, doesn`t think she should follow 50-year-old Moore`s advice.
"Justin thinks Jen is perfect, and the only thing wrong with her are some of her friends," the source said.
