SCARLETT IS PISSED !

Us Weekly reports that Scarlett Johansson has had plastic surgery, a claim the actress vehemently denies.

ScarJo is very upset and threatening legal action.

Her publicist tells competing mag, OK!:

"Us Weekly's [new] cover story regarding Scarlett Johansson and its clear implication that she has had plastic or cosmetic surgery on her nose is an outrageous and defamatory fabrication lacking any conceivable basis or proof, despite vehement denials by Ms. Johansson prior to publication. Not surprisingly, US magazine cannot provide the dates when she supposedly had this surgery, who performed the surgery, or what was supposedly done - all because there simply is no truth to the story. The publication made a pathetic attempt to validate its story by using two cover photos of Scarlett that were taken years apart with obviously different make-up and lighting, and then relying on an "expert's opinion" (based solely on looking at the two photos) on what "might" have been done. It wasn't."

Johansson herself says, "I have always been straightforward with the press regarding my body image and I am very concerned that my fans (and perhaps even my employers) will feel mislead. Thus, I feel compelled to take immediate legal action against US Weekly."
