While filming "The Other Boleyn Girl," the curvaceous 23-year-old actress became visibly agitated after overhearing several crew members say she looked like a "grungy teenager," the source told the Daily Mail.
"Scarlett had just been voted the world's sexiest woman by a men's magazine," the unidentified source said. "Some of the crew were laughing that she looked more like a grungy teenager.
"Scarlett lost her temper; it was pretty uncomfortable."
The British newspaper also reported Sunday Johansson is rumored to have become engaged to actor Ryan Reynolds, although the celebrity couple has yet to confirm such reports.
