In a world where celebrities regularly wear realistic hair extensions and have hairstylists on call, it's easy to assume they wake up that way. So when Jennifer Lopez shared a snap of her short and imperfect natural waves, it reminded us that stars are just like us.
In the last year - alongside the trend of no make-up selfies - stars have embraced their natural locks by sharing pictures of their untamed hair on Instagram and speaking about it in interviews.
From JLo to Nicole Kidman to Beyoncé, we take a look at the stars who have momentarily cast aside their straighteners and extensions to reveal their true hair…
She's normally photographed with long, ombre locks, but during a short break from work in New York, Jennifer Lopez shared a snap of her cropped and wavy natural hair, writing "#curlyhairdontcare #myNYlook".
The actress, known for her glossy long mane, posted her first and (so far) only image on Instagram, showing her hair soaked in rain water.
The star said she prefers her hair "to look really relaxed" and that it's her "safety net" in an interview with Refinery 29. "You'll see people on the red carpet with structured hair and to me that just makes me feel stiff and uncomfortable. If I have my hair down...I feel like it looks lived in, it feels like it has a story."
She added: "When I wash and dry my hair - I have naturally wavy hair - so I'll dry it so that it's still a little bit wet and then I'll put it in a ballerina bun and then when i take it out it has a really nice natural deep wave".
After years of loathing her ginger curls, the actress - who's made long blonde hair her signature look in the last decade - has learned to finally embrace her natural hair. “I almost never straighten it anymore,” she said in an interview with American InStyle. "It’s taken me 40-something years, but I embrace the curl. My littlest daughter has the same hair. She likes it when my hair is curly, so I wear it for her."

Since Rihanna burst onto the music scene in 2009, she's had hundreds of hair styles from the short bob in her 'Umbrella' video to a statement-red mane in 'Only Girl (in the World)'. The hair chameleon shared a series of images of her natural short, black and curly locks in August 2013.
From blonde to brunette and waves to braids, it's virtually impossible to know which of Beyoncé's styles are her natural hair or a wig. That was until the singer shared a series of pictures on Instagram displaying a new pixie crop in August 2013. Her long-term hairstylist Kim Kimble, quashed any criticism over the legitimacy of the image, saying, "I got a little teary eyed (when she saw the Instagram post)! I’ve been working for her so long, she has this beautiful long hair and it’s hard to grow hair out...Maybe I’ll cut my hair off now. Short hair, don’t care!"
In April 2014, a rare picture revealed what is thought to be Kim Kardashian's natural hair length. Posted by Balmain creative director Olivier Rousteing, it featured the star with shorter hair. Within a few days Kardashian was photographed with her trademark longer dark hair once again.
In May 2013 the platinum blonde star tweeted a throwback picture of her natural brunette hair writing, "Ha... little Rita!" When a fan sent the singer a screen grab of herself acting as a 14-year-old in British film Spivs on Twitter in 2012, she replied, "HAHA before bleach!"

The American television personality and former model dropped her wig and extensions on her self-proclaimed "National Real Hair Day" in 2009 on Instagram and on her talk show.
Actress Gabrielle Union, best known for her roles in Bring It On and Bad Boys II, posted an image of her untamed hair on Instagram, writing: "Ladies…you can achieve hair growth…With a weave! This is allllll mine, no clips, no extensions, hadn’t even been pressed…And it got this healthy thick length from responsibly wearing weaves."
