Scarlett sees red over "grungy teenager" remark

Scarlett is often voted one of the world's sexiest women.

Scarlett Johansson may have no shortage of male admirers - but she still has moments of insecurity about her looks.

    The pert 23-year-old treated some technicians to the sharp side of her tongue during filming of her latest movie "The Other Boleyn Girl" when she overheard them discussing her appearance.

    "Scarlett had just been voted the world's sexiest woman by a men's magazine," said a source.

    "Some of the crew were laughing that she looked more like a grungy teenager.

    "Scarlett lost her temper, it was pretty uncomfortable."

    Clearly actor Ryan Reynolds, 31, finds Scarlett alluring - according to Hollywood gossip the pair got engaged last month.
