Scarlett Johansson is probably as well known for her curvaceous figure as for her body of work. In fact, just last month she was quoted in "In Touch" as saying she'd never dieted and or set foot inside a gym. It's not like she always sat around eating cookies -- she has simply made a point to eat well and walk a lot, at least, until now.

Suddenly, ScarJo (who was recently named as the first celeb ambassador to Moet champagne -- bet she's not drinking much of that!) is noticeably slimmer, and was overheard talking to fellow actress Thandie Newton about the rigid diet she's currently following, apparently in order to get ready for "Iron Man 2." I don't know about you, but I have a hard time imagining any director asking Scarlett to lose weight.

Truthfully, the right bra and makeup can make a pretty big difference, but I don't think there's any denying that there's now less of Scarlett to love. She doesn't look unhealthy, but she definitely looks different, as is pretty evident above (the picture on left is from this past December while the one on the right was taken last week).

What do you think about Scarlett's new body?
