Helen Flanagan's cups nearly run over as she wears a revealing basque

When it comes to revealing outfits, few celebrities are as well versed on the subject as Helen Flanagan.

And whether she's walking the red carpet or attending a campaign event, Helen doesn't discriminate with her barely-there looks.

The latest such ensemble consisted of an incredibly low-cut white lace Agent Provocateur basque, which the 22-year-old star teamed with skintight jeans.

Helen chose the outfit as she launched her new advert for animal rights group PETA, in which she poses naked and covered in reptilian body paint in the new campaign.

With her famous cleavage on full display, Helen placed her hands on her waist and leaned forward in a bid to further enhance her curves in the £245 corset.

The pretty young star finished off her look with a pair of vertiginous heels, and kept her make-up simple with a slick of mascara and lipgloss.

A group of onlookers were seen looking bemused by Helen's outfit choice as she posed up next to a large cardboard print of her advert.

And even Helen appeared taken aback by the shot, looking at it nervously as she posed up for photographers.

The image, shot by celebrity photographer Trevor Leighton, features Helen naked apart from a slick of body paint and strewn across a large rock.

Next to Helen is a reference to her time on I'm A Celebrity.. Get Me Out Of Here!, with the slogan 'Exotic Skins Belong In The Jungle'.

Speaking about her decision to star in the campaign, Helen said: 'Spring is the perfect time to clean the cruelty from our closets.

'I know when people see PETA's video, they won't want anything to do with the exotic-skins industry and will join me in leaving wildlife out of their wardrobes.'

In an interview with MailOnline earlier this month, Helen insisted that her boyfriend Scott Sinclair doesn't mind her doing sexy photoshoots.

She said: 'I really, really enjoy my photoshoots and I'm not shy, as everyone knows. It's good fun. If everything is really classy and beautiful and tasteful, I don't think there's anything wrong with sexy shoots.

'I think women should celebrate themselves as beautiful and sexy. It's a positive thing. Scott would never tell me what to do and what not to do and vice versa.

'I think it's important when you get together when you're young to do your own thing and focus on your career.

'I don't think I could be with someone who was going to dictate to me what we do.'

However, Helen's sexy image at Thursday's photocall was somewhat ruined by her hair extensions - which were clearly visible beneath the actress' eye-wateringly tight ponytail.

The hairstyle further highlighted the clumps of extensions, but Helen appeared either unaware or unconcerned about the faux pas as she posed next to the advert.
