Scott Disick is proving the saying 'a leopard never changes its spots' right!

Los Angeles - Scott Disick is back to his partying ways.

The Keeping Up With The Kardashians star has reportedly gone "back to spiralling" after being spotted looking a little worse for wear in New York.

A source said: "Scott is still in New York, and he's a mess again. From the minute he touched down, he's been a trainwreck.

"All anyone can assume is that he met up with the wrong people - people who don't really care about his well-being - and one drink led to another which led to another. None of these people give a damn if he's healthy or not. They just want to party. Scott's back to spiralling."

The 32-year-old television personality is also said to be struggling to cope without his ex-partner Kourtney Kardashian, with whom he has Mason, six, Penelope, three and Reign, 14 months.

Another insider added to E! News: "Scott has been going out every night and drinking again. He has been partying hard. After a few months of being on his best behavior, he cracked.

"Scott is so used to Kourtney taking him back every time, but this time has been different. Scott is already falling back into his old partying habits. Kourtney is not impressed."
