Since Adele posted that birthday snap, a social media firestorm has ensued. Now, Sharon Osborne has been slammed for her comments...

This week, Adele shocked the world.

To commemorate her thirty-second birthday, the British singer shared a rare Instagram photo that showed off her remarkable weight loss.

And she looks incredible.

Adele has had a long journey with her weight-loss, and most people were delighted to see her transformation, and were quick to shower her with compliments.

Although many comments have rubbed people up the wrong way...

And Sharon Osborne's are the latest to spark backlash.

But let's start from the beginning.

Regardless of her appearance, the London-born singer has been an unstoppable force in the music scene for the past decade.

All her albums have been hugely successful.

19, along with her second follow-up album 21 earned her immense critical praise, and the success of both the albums cemented her firmly in the industry.

And things only went up from there...

After taking a break to focus on her personal life in 2012, Adele returned back to the scene with her sensational hit "Hello."

And that became the song of the year in 2015.

Shortly after, she released her next album, 25, which featured iconic songs such as "Send My Love (To Your New Lover)." If you haven't listened to that album, please do yourself a favor and add it to your playlist. You will not be disappointed.

Now, the singer has sold millions of songs worldwide.

Her list of achievements is outstanding, to say the least. Adele has fifteen Grammys as well as an Oscar tucked nicely under her belt and the list is expected to grow as rumors of her next album have sparked fans interest.

But there's another reason fans can't get enough of Adele.

She has a truly infectiously hilarious personality. If you're looking for a down-to-earth star, Adele is it.

She is known for staying true to herself.

And, in the last year, fans have been noticing a dramatic change in her appearance.

Adele has always been gorgeous, but she always been open about how she wasn't happy with her body...

And that's fine. Everyone's allowed to have their personal goals about what they want to look like. It doesn't take anything away from her amazing talent as a singer.

But, in the last year, Adele has reportedly been working hard to lose weight.

The pop icon has had a long battle with her weight, but this last year, she has really been driven to lose the pounds for good.

Adele is also known for being quiet on Instagram...

And the star is rarely very active on social media.

In fact, it's rare if we get a sighting of her at all.

Which is why her most recent post has shocked fans to their core.

Now, in the last couple of months, we have all noticed a slight change in the singer's appearance...

She is quite visibly losing weight, but her most recent update is the most eye-opening of them all.

Adele has just celebrated her thirty-second birthday...

And we must say, she is looking better than ever.

Fans are living for her new look...

And many have even begun asking if a new album is in the works... Which we are also hoping for, by the way.

It has truly blown our minds...

Brace yourselves, you're going to be truly shocked.

Here is the infamous and very beautiful photo.

Adele looks completely unrecognizable, yet completely amazing in her latest snap, where she dons a figure-hugging black mini-dress. She captioned the post with: "Thank you for the birthday love. I hope you’re all staying safe and sane during this crazy time. I’d like to thank all of our first responders and essential workers who are keeping us safe while risking their lives! You are truly our angels."

Obviously, people have been going wild about her shock transformation.

And the photo quickly went viral, with millions of people showering the singer in compliments and praise for her incredible achievement.

But others haven't been so kind.

Some spiteful Twitter users have been claiming that Adele's weight-loss is a bad thing, that we "bullied" her into it, and that she looks "sick."

People have been truly resentful about her weight loss.

It seems that some people just can't stand the idea of a woman wanting to change her body in a healthy way.

Many seem to think that Adele has only lost the weight to fit societal standards...

God forbid she would ever lose weight because she wanted to.

Adele's former personal trainer called the comments "disheartening."

Writing on Instagram, he began: "As Adele's former London-based personal trainer, it's disheartening to read the negative commentary and fat-phobic accusations questioning the genuineness of her amazing weight loss."

He has stressed that Adele does things her way.

"In my personal experience of working with her through many highs and lows, she always marched to the beat of her own drum on her own terms. She never undermined her God-given talent in any way. She let her incredible voice do the talking, or should I say singing!"

And he explained that, for Adele, her goal was never to lose weight...

Her goal was to be healthy. "When Adele and I started our journey together, it was never about getting super skinny. It was about getting her healthy. Especially post-pregnancy and post-surgery. When 25 dropped and the tour announced, we had to get ready for a thirteen-month gruelling schedule. In that time, she warmed to training and made better food choices. As a result, she lost considerable weight and people took notice."

And she isn't losing weight to live up to society's standards...

Geracimo continued: "She embraced better eating habits and committed to her fitness and 'is sweating'! I could not be prouder or happier for her! This metamorphosis is not for album sales, publicity or to be a role model. She is doing it for herself and for [her son] Angelo."

And the trainer could not be happier for her.

"My hope is that people appreciate the hard work that Adele has done to improve herself for the benefit to her and her family only," Geracimo wrote as he wrapped up his message. "She did not lose the weight to make others feel bad about themselves. This personal transformation has nothing to do with me or you. It's about Adele and how she wants to live her life. She has not changed from the Adele we grew up with and have loved. There is just a little less of her to go around."

However, it seems that this week, one celebrity has come under fire for her comments about Adele's weight loss.

On Tuesday, Sharon Osbourne and the other ladies of The Talk weighed in on Adele's Instagram pic. 

And the internet is not happy with what Sharon had to say.

The star praised Adele for her weight loss, saying she looks "absolutely fantastic," and went on to say she doesn't believe "really big women" are "really happy in their body." Yikes.

She continued:

"Because I was really, really big [once] and I wasn't happy," Sharon continued. "Sure, on the surface, ha, ha, but at night, in bed, alone, I was very unhappy."

In 1999, Sharon underwent gastric band surgery, which helped her lose one-hundred pounds...

She then had the band removed in 2006. "I am happy for [Adele] and everybody should be happy for her, because it was her choice. She didn’t do it for anybody else but herself. And so everybody should be happy for her," she added.

But it seems Sharon hasn't taken into consideration what other people are saying.

People rarely wake up one day and think, "the body type I have is wrong." That ideology is taught through society telling us what size we should be or through other people's bullying or remarks.

Some said that happiness and self-esteem have nothing to do with your body.

"Unfortunately in the current day I think too many people are not happy in their own bodies, but that’s not down solely to weight, unfortunately we are living in an escalating superficial society striving more and more for an unrealistic appearance."

Some raised this point.

Why can't someone be happy with themselves if they are "bigger"?

Although, some had a different take on Sharon's comments.

Many people defended Sharon, pointing out that not only did they feel she was speaking a truth "many didn't want to hear," but that she was drawing in on her own experiences with weight loss.
