The `One Day` actress - who is a committed vegetarian - has been eating the nutritious form of cabbage to ensure she gets in shape to play Catwoman, who traditionally wears a skintight catsuit in Batman movies, in forthcoming film `The Dark Knight Rises`.

She told talk show host Chelsea Handler on `Chelsea Lately`: "I`m a vegetarian and right now, I`m living on kale and dust for the training. That catsuit`s unforgiving, man!"

The 28-year-old beauty - who has been doing Bikram yoga as part of her Catwoman training - explained she now "really likes" working out, whereas previously she found it tough to get over those "workout humps" where every exercise is "painful" to do.

She added: "Last time I was here we talked about how much I really don`t like working out. I really like it now. I know, that`s like, ugh? that person.

"Like, I came to LA, got a bikini wax, went blond and love working out.

"There`s a workout hump where you`re so weak that you hate everything and everything`s painful, and you look like an idiot.

"Like, the gym that I work out at, I was literally working out next to a pregnant Jessica Alba, and she could do more pushups than I could!"
