The Lord needs some serious help, but not if you ask him!

Scott Disick is allegedly lying and downplaying the extent of his substance abuse to concerned friends, and they fear that he's going to get even more out of control now that he's split from Kourtney Kardashian.

"There's no real incentive for him to get himself together. When he's gone to rehab or sought treatment for his issues, it has been after an ultimatum: Get treatment or it's over. If it's over, there's no real incentive for him to get himself together," a source told People.

The father-of-three went to rehab earlier this year, and now maintains that his alcohol use is not an issue. "Scott insisted that his drinking is under control, that he's not in a spiral, but everyone around him knows the truth. He has been lying to everyone, saying that he's clean and sober ... and he insists that he doesn't have a problem," the source added.

Making matters worse, LD is hosting a party at 1OAK in Las Vegas this Friday, and was stupid enough to promote his appearance on his Instagram just days after he was dumped by his baby mama. Maybe he will party it up in Sin City sober?! NOT!

Update: Scott just removed his Las Vegas appearance Instagram post. Is the backlash too much to handle? Or is he canceling to protect his image? Guess we will have to wait and see!
