Cheeky Kendall Jenner gets past Instagram's nipple ban with some strategically placed pizza emojis  

She's certainly not shy about flashing her breasts, previously confessing that she is 'all about freeing the nipple'.

And Kendall Jenner found a cheeky way to get past Instagram's nipple ban on Saturday.

The 21-year-old, who celebrated her milestone birthday on Thursday, shared a flashback photo on the social networking site.

'Zaza': Kendall Jenner found a cheeky way to get past Instagram's nipple ban on Saturday... with some strategically placed pizza emojis 

The snapshot showed just Kendall's chest and torso as she sported a sheer black top, with two pizza emojis strategically placed to cover her nipples. 

The reality star turned model, who also wore jeans and a choker while her face was cut off from the photo, captioned it simply 'zaza'.

Last month, Kendall said that she wasn't too nervous for her first catwalk show in 2014, when she walked for Marc Jacobs, because she was clad in flat shoes.

'My biggest concern was definitely falling. And then my t*ts were out,' she told W Magazine.

Keep it casual in Kendall's Re/Done jeans

Kendall Jenner may have given onlookers a little more than they bargained for in her semi sheer top, but we couldn’t take our eyes off her fab jeans!

With a high waist and slim line leg, this style of Mom jean is super flattering and great at creating all the right proportions on both slim and curvy figures.

Kendall’s jeans are by a label called Re/Done who take vintage Levi’s jeans and deconstruct the denim to create brand new designs.

'I don’t know why I wasn’t nervous about that. I was really excited about my t*ts being out, actually.'

Kendall added: 'I'm weird. I love my t*ts being out. It’s like one of my things, I guess.'

The previous month, the Keeping Up With The Kardashians star had dedicated a post on her website kendallj.com to her love or baring all.

'Lately, it's like I'm either braless or I have my bra out, lol. I'm all about freeing the nipple!' she wrote. 

'I love my t*ts being out': Last month, Kendall discussed showing her breasts under her top during her first catwalk show for Marc Jacobs in 2014

'I just think it's cool to show off what's under your shirt—whether that's a cute bralette or just skin. ;)'

Free The Nipple is a gender equality campaign named after Lina Esco's 2014 film of the same title, arguing that women should be allowed to show their nipples in public, as men are. 

Meanwhile Kendall celebrated her 21st birthday with a star-studded party earlier this week, and her sister Khloe later revealed that the model was so 'drunk' she forgot she had been given a Rolls Royce.
