Amy Adams shows off her post-baby body after pole dancing her way back into shape

She may have a reputation for being somewhat straight-laced, but it seems Amy Adams has a racy side.

The actress has revealed that she got her body back into pre-baby shape by taking pole dancing classes, after giving birth to daughter Aviana, in May. 

'Some mum friends said it's a good way to lose the baby weight,' she said. 'And I'll do anything to get off of that treadmill.'

Back in shape: In the January edition of Marie Claire, Amy Adams revealed she got back into pre-baby shape by pole dancing

The actress made the revelation in January's U.S. edition of Marie Claire, for which she posed in a daringly low cut top.

But while she is throwing herself back into exercise, Amy claims she is not overly concerned with pinging back into her pre-pregnancy shape.

'Women can be really hard on one another about weight,' she says.

'Someone came to my [baby] shower and said, "Oh, my gosh. That's a lot."

'I'm pretty comfortable with my body and I was comfortable with the weight gain, but that's not what you want to hear.'

The 36-year-old redhead, who once played a nun onscreen, also claimed that she is not as innocent as people assume.

'I did one interview when I was pregnant, and the writer said he thought people would be surprised to know that I had sex.

'I didn't know what to say. I was like, "Excuse me if it takes a minute to process the fact that you think I'm asexual."

'Anyway, there's something great about the world thinking I'm so innocent. Only it's not true.

'In my 20s, boy. I was a hot mess.'

Amy, engaged to her daughter's father Darren Le Gallo, was born to Mormon parents  and has played a variety of wide-eyed characters onscreen.

She played a nun opposite Meryl Streep in Doubt, was a princess in the Disney hit Enchanted and an innocent Southern girl in Junebug.

In her latest film - The Fighter - Adams says she plays a person who is closer to her true self.

She plays Charlene - the bartender who dates a struggling working-class boxer, portrayed by Mark Wahlberg.

The film's director David O Russell tells Marie Claire that he chose Adams for the role because he knew she could play 'a tough, sexy b****.'

The actress agrees, saying: 'What's funny is that some people who've seen it have said: "Amy, you're finally playing yourself".

'It's not that she's less naïve. My other characters haven't been tested.

'She has been through it.'

When she was growing up Adams says she had a very definite idea of what an attractive woman looks like.

'I grew up in Colorado in the Eighties,' she said. 'So I was into metal. My idea of sexy was [actress] Tawny Kitaen in that Whitesnake video.

'Back then strong and muscular was sexy, like Cindy Crawford.

'Women wanted to take up more space with big hair and shoulder pads. Emaciated wasn't sexy at all.

'Technically, I'm a petite person. But I've always been strong.

'And I've never been into deprivation. Those bones that show in women's shoulders when they're extra skinny?

'I never had that, even at my thinnest. I don't even think I have those bones.'

In the meantime, in her private life, Adams says she has yet to pin down a date to wed her fiancé

'Darren and I would set a date, and then a project would come up and we'd push it," says the actress who got engaged in 2008.

'Then when we got pregnant, we were going to get married right away.

'And we will get married. But we didn't want to rush and plan something just to do it the traditional way.'
