Kelly has not spoken recently about her weight loss, but she has previously opened up about losing over 40 pounds.

After she shared the sizzling new snap her 7.2 million quickly took to the comments, with one writing, 'Guuuurl look at all that weight you've lost!!! So proud of you!!!'

'You look absolutely gorgeous! Get em girl! Welcome back!' another thrilled fan applauded.

Many of Kelly's followers speculated about her possibly using the help of Ozempic to achieve the slimmed down look.

'What in the Ozempic is going on up in here?' someone questioned, while another person added, 'Ozempic face.' 

Yet another fan wrote: 'Wow. You look amazing. I'm on ozempic and have lost 90 pounds. It's the best thing in my life.'

'Ozempic looks good on you!' someone else chimed in, while another added, 'Ozempic works wonders!'

However, others disputed the Ozempic claims, writing that a number of other factors could have contributed to the weight loss.

'I know y'all out here accused out queen of taking diet pills but every woman's body can change overtime due to stress, ptsd, pros, or naturally by working out. Even if Kelly took diet pills. It's not your body or business to judge.'

Comments continued to pour in about her incredible look, with one fan writing, 'Look at you!! Glow up doll!!!' 

Kelly, who won the first season of American Idol in 2002, also showed off her slimmed down form while attending the We Can Survive concert in support of mental health awareness on October 14. 

In 2020 she admitted that she felt 'more pressure' in the music industry when she was thin.

The Since U Been Gone singer said that she used to be shown naked magazine covers of women and told 'this is what you're competing with'.

'I felt more pressure. It was more of magazines shoved in front of you and, 'This is what you're competing with and we've got to compete with it. I can't compete with that. That's not even my image. That's not who I am. That's who they are,' she told . 

Kelly and her ex Brandon were married for seven years before they split up in 2020, setting off a protracted bout of legal squabbling over money.

The divorce dragged on for a year and a half before it was ultimately finalized in March of 2022.

The divorce led to a brutal custody fight between the exes, with Clarkson eventually securing primary custody.

Kelly released a bitter break-up album earlier this year called Chemistry that detailed the 'good, the bad and the ugly' of her relationship with Brandon. 

She recently moved to New York City with their children for a 'fresh start' and will now hosts her self-titled talk show out of the Big Apple.
