Anything is okay as long as it's done by consent, and shared by intention. Otherwise, it is not.
Sex tapes, for example. Most of them, especially those that involve celebrities, were uploaded to the internet without their consent and intention.
But social media posts are different.
Usually, celebrities would try to look good when posting something on Instagram. High-profile celebrities even have a dedicated team just for this, who work tirelessly to get the perfect shot, and retouch them to make them perfect.
But Selena Gomez isn't like those kind of people, even when she is indeed a prominent figure on Instagram.
And this can be an issue.

Born in 1992, Selena Marie Gomez is an American singer, songwriter, actress, producer, and businesswoman.
She began her career as a child actress, before rising to prominence and emerged as a teen idol, before becoming a lead vocalist, and formed her own band, and went solo.
With over 429 million followers, Selena is the first woman with that many followers, the most followed musician, actress, American, and North American female on Instagram.
Her popularity on social media is a testament to her widespread influence and appeal.
With so many accounts (and eyes) following Selena on Instagram, a mishap quickly spreads.
This happens when the singer nearly suffered a wardrobe malfunction as she shared some racy snaps.
In the photos, Selena, who took selfies from her Los Angeles home, wore a skin-tight black bra as her top cut low and pushed up her ample cleavage.
Selena's brunette locks were styled and fell over her shoulder.
The star wore glamorous makeup which she completed with a bright red lip.
She accessorized with gold hoop earrings.
Her simple text tattoo was visible on her inner arm.

Selena deleted the photos a few hours after posting them.
While the photos didn't reveal anything, and that the star didn't provide an explanation for her removal, some internet users suggest that she was suffering a wardrobe malfunction.
Selena is known for defending her body after receiving criticisms, but having a glimpse of her areola might not what she had in mind.
Selena deleted the photos, but just like always, the internet is faster.

So, despite swiftly taking down the picture, Selena faced critic, and not to mention, bullies.
But quickly, her fans gathered and got her back.
It didn't take long before her loyal fans came to her defense, showering her with support.
Putting aside her bosom area, her fans defended her for her looks. In the photos, Selena looks a lot fuller, and appears as if she has been gaining a lot of weight.
Her voluptuous figure can be attributed to an autoimmune disease called systemic lupus erythematous she is having.
Selena has been open about her weight fluctuations, attributing it to the medication she takes to manage the disease, which can cause inflammation in various parts of the body. The medications used to treat lupus can have side effects, including weight gain and water retention.
In 2017, Selena went on a [YouTube] live stream to address comments about her appearance. She said that she tends to hold a lot of water weight when she’s on her medication, and that it flutuates when she’s not taking it.
The pop singer admitted that she will never be extremely thin again.
