(Cover) - EN Showbiz - Anne Hathaway has joked she's living on dust to get into the "unforgiving" Catwoman suit.

The actress appears in the upcoming Batman film The Dark Knight Rises. She wears a skin-tight black jumpsuit for much of the movie, meaning she's had to go on a strict diet.

Anne explained cutting out certain foods isn't the worst thing about the situation. The shoot is running over six months, so must feel confident enough to wear the outfit during that time.

"I'm a vegetarian and right now I'm living on kale and dust. The catsuit's unforgiving, man. It's a lot of motivation. It takes three of us to get me into it," she laughed to talk show host Chelsea Handler.

Anne has also upped her exercise programme so she feels body confident. Previously she's admitted hating working out, but she's now grown to enjoy it. The 28-year-old likes pushing herself, even though at times she's found it embarrassing.

"Last time I was here we talked about how I really don't like working out. I really like it now, that's changed. I know, it's like, Eugh.' I feel like that person, like I came to LA got a bikini wax and went blonde and love working out," she said. "Actually I think I had never really gotten over the hump. There's a workout hump where you're so weak that you hate everything because everything's painful and you look like an idiot. The gym I work out at I was literally working out next to a pregnant Jessica Alba, and she could do more push-ups than I could!" (C) Cover Media
