Kourtney Kardashian's ex Scott Disick looks gaunt while celebrating his 43rd birthday after admitting to taking GLP-1s

Kourtney Kardashian's ex Scott Disick looked gaunt when leaving Nobu in Malibu on Tuesday evening.

The Kardashians star was celebrating his 43rd birthday with his children Reign, Mason and Penelope, whom he shares with ex-partner Kourtney Kardashian.

Kim Kardashian and her new boyfriend Lewis Hamilton were also spotted at the swanky restaurant, as was Kris Jenner. 

However, there was no sign of Kourtney, who split from Disick in 2015. She is now wed to drummer Travis Barker, who was similarly absent from the festivities. 

Disick's shockingly slender frame could be due to his GLP-1 use. For the past year the reality TV star, who also goes by Lord Disick, has been hawking a company that sells the weight-loss shot online.

In April, promoted the platform Omzo on his popular Instagram account. 

'When it comes to my health, I like things done right,' he wrote. 'That's why I use @omzo.us #omzopartner.' 

Omzo provides licensed clinicians to help create 'custom weight-loss plans' for subscribers through the platform, combining 'proven treatments, nutrition guidance and GLP-1 support' while using clinician-approved medications, including Semaglutide and Tirzepatide, per their website.

In February 2025, Disick accidentally revealed he was taking the weight-loss medication Mounjaro when boxes of the drug could be spied in the top section of his refrigerator.

Scott has reportedly found it difficult to watch Kourtneymove on with Travis, and famously blasted their PDA in a leaked DM in 2022.

Insiders have claimed the troubled star is in a 'dire situation' with talk of an intervention after his Ozempic use has left him looking shockingly gaunt.

'Kourtney’s marriage to Travis took a toll on Scott and as he got bigger he was comparing himself to Travis – and Travis being thin didn’t help,' a source told DailyMail.com exclusively. 

'Scott turned to food as his crutch because he could not turn to drugs.'

The insider added that the star shunned alcohol and drugs as a means of coping, stressing that the Keeping Up With The Kardashians star does not want to jeopardize his relationship with his children.

'He loves his kids too much to try to ruin his relationship with them,' the source said. 'Kourtney is of course concerned because he is the father of her children.

'After the photos emerged, people close to Scott realized how dire the situation is – but they’re struggling with an intervention as so many around him take the drug too. It would be like the pot calling the kettle black.'

Scott dated Kourtney from 2006 to 2015, with the reality TV star citing his sobriety battles as the reason for their split.

Kourtney moved on with drummer Travis, with the pair tying the knot in May 2022. The couple, who are no strangers to very public displays of affection, welcomed their first child together, son Rocky in 2023.

In 2024 DailyMail.com reported that Kourtney is reportedly concerned for Scott, who insiders claim has gone 'too far' with Ozempic in a desperate bid to get rid of his 'dad bod.'

Scott, who lost his parents in 2013 and 2014, has openly struggled with substance abuse and alcoholism.

But an insider said: 'He is not ill and isn’t doing hardcore drugs. Kourtney would never allow Scott to spend so much time with their kids if he was in the throes of an addiction.

'Scott started taking Ozempic because he had serious issues with his weight gain. This time last year he saw himself as fat. 

'He had gained a lot of weight and couldn’t stand seeing himself in video footage that aired in the past couple of months. He would go to great lengths to cover it up.

'Scott wanted the easy way out of his dad bod. But now it has clearly gone too far and, of course, the family is worried about him.'

The source added: 'They will likely use this for show ratings in The Kardashians. Scott is strong and will be able to get through this – especially now that he knows that it has become a huge problem with his image and fame.'

Scott's wellbeing became a topic of conversation last year following an episode of the popular Hulu reality show in which Khloe voiced her concerns for his health after he suffered a back injury.

The star's struggles began in August 2022 after a car crash which left his Lamborghini flipped upside down. 

During the episode, Scott admitted he had not been doing the physical therapy needed to recover and later told his doctor: 'I haven't been able to run around. I've gained weight.'

Khloe Kardashian said: 'I think Scott needs a little pep talk because this is probably the unhealthiest I've seen him. He's barely mobile, and it's all from his back, so that wouldn't make anyone feel good.'

Scott then admitted that he had 'gained a lot of weight... because of my back.'
