Kate Winslet got digitally altered to look skinny — and there’s a lot of finger pointing going on over who’s responsible.

The “Titanic” star is one of the few celebs who has said she’s happy with her extra curves.

“What is sexy?” Winslet says in an interview with current British GQ. “All I know from the men I’ve ever spoken to is that they like girls to have an arse on them, so why is it that women think in order to be adored they have to be thin?”

So Winslet’s fans were shocked and dismayed by the pics accompanying the article [click each image for enlargements], which showed her with an impossibly slim waist and no arse to speak of.

Winslet herself blasted the magazine for tinkering with her extra pounds. “It’s an outrage,” the star complained to one paper. “The re-touching is excessive. I don’t look like that and I don’t desire to look like that . . . I haven’t suddenly lost thirty pounds.”

But Winslet’s outrage may be a tad disingenuous. According to PeopleNews.com, the star actually approved the slimmed-down pics.
