What in the world is happening to Scott Disick?

After making headlines in May for hooking up with multiple girls during the Cannes Film Festival, the father-of-three has been non-stop partying for two months straight — and it’s become deeply concerning to those closest to him.

“Scott is in the worst shape he’s ever been in,” a source tells Life & Style exclusively. “Friends and family fear he’s headed for an overdose.”

Unfortunately, the 34-year-old has been in this position before. In 2014, he was rushed to the emergency room after ingesting a potentially lethal combination of cocaine, Xanax, and alcohol, his former manager, David Weintraub, told Life & Style.

And in January 2016, Scott was found unresponsive after downing cocaine, vodka, beer, and Viagra, an insider shared. He had to be revived with an adrenaline shot.

A confidant tells Life & Style that the reality star, who’s frequently around cocaine and other drugs, “can drink five days in a row with barely any sleep.”

As fans have seen, Scott’s baby mama, Kourtney Kardashian, made it clear that she’s given up trying to get him sober. “She’s done everything she can to help, and he’s rejected the efforts. The only person who can save Scott now is himself,” an insider notes.

The car enthusiast has recently been linked to 19-year-old actress Bella Thorne, and many are calling the much older KUWTK star a bad influence on the Disney Channel alum. “They both love to party and that is the sole reason why they hang out with each other. It is pure fun,” a source previously told E! News.

“Scott knows that he is getting a rise out of the public and is sparking attention on himself when he hangs out with Bella, or any other young girl. He loves it.”
