London, Oct 1 Scarlett Johansson says she is her natural self whenever she is modelling, because trying to act sexy is "most unsexy".

The Sun quoted her as telling Glamour: "I don't think about being sexy, being seductive.

"What you don't want to see is somebody trying to be sexy. That's the most unsexy thing."

The 24-year-old hottie says she is at her critical best when she's seeing her own snaps.

"I have my funny moments where I look at myself and think, 'Oh, this is a disaster,'" she adds. (ANI)
