Lately, it seems like we've been getting a glut of actress versus actress stories in the tabloids. The latest report from the National Enquirer states that Charlize Theron is actually worried that Scarlett Johansson will 'steal' her Dior contract.

Charlize is one of the Dior representatives, along with Mila Kunis, Marion Cotillard, Jennifer Lawrence, and Robert Pattinson. According to the report, the executives of Dior are 'worried' that Charlize is not 'French enough', while Scarlett is apparently continuing 'her love affair with all things French.'
The 'source' explains, "Scarlett adores Paris and has spent months there with Romain. Besides that, the French have really responded to her photos in Vanity Fair, especially one shot that’s reminiscent of Brigitte Bardot.” The source then adds, "Charlize has done really well for Dior, but the company has to stay fresh… they’re worried that Charlize comes across as too aloof and are looking at Scarlett as a possible replacement.”

Scarlett Johansson to land Dior deal?
This seems rather silly, doesn't it? There have been plenty of reports about in-fighting between actresses over contract deals with major fashion houses, but it certainly seems like brand has enough products for an extra actress. If Dior wanted Scarlett Johansson, I doubt they would replace Charlize, but rather give Scarlett another Dior product to represent.
