麦莉·赛勒斯(Miley Cyrus)不戴文胸逛商店 - By Jade Watkins,14 April 2012

She flashed quite a lot of her navy blue bra last week as she left the gym in a sleeveless white top.

And it was no different on Tuesday as the Hannah Montana star went shopping with her mother wearing one of her favourite rock T-shirts.

However this time the 19-year-old star exposed her part of her modesty as she opted to go bra-less for the outing in Calabasas.

Perusing through the clothing store, Miley's side boob was on show for all to see through the gaping sides of her Iron Maiden customised top.

She had taken off her yellow studded biker jacket that she had been wearing to try on some clothes.

The actress and singer paired her oversized vest with a pair of high-waisted denim jeans and some mid-length leather combat boots.

She bundled her brunette locks in a high bun and wore her favourite Ray-Ban shades.

This week Miley furiously maintained that she is not, in fact, anorexic, after a series of reports suggested that she was suffering from the eating disorder.

She took to her Twitter page to debunk the rumours, claiming her weight loss was due to a dietary allergy.

Miley wrote: ''For everyone calling me anorexic, I have a gluten and lactose allergy,' she wrote on her Twitter account. 'It's not about weight it's about health. Gluten is crapppp anyway!'

She told one fan: 'Everyone should try no gluten for a week! The change in your skin, physical and mental health is amazing. You won't go back!'

Miley's frame has been noticeably slimmer lately - in comparison to just seven months ago during a performance on stage in November.

Fans of the former Hannah Montana star became concerned about the star after after she recently tweeted a photograph of herself inhaling the contents of a Carl's Jr takeout bag.

She wrote underneath the picture; 'I can't eat it. So I'm just gonna smell the s*** out of it! My mouth is LITERALLY watering.'

The star has previously spoken out over the pressure on women to look a certain way.

Back in December she tweeted: 'By calling girls like me fat this is what you're doing to other people. I love MYSELF & if you could say the same.'
