Scott Disick is back on the booze, and it's ugly

Scott Disick is back to his old partying ways.

Eyewitnesses tell Page Six the reality star caused a drunken scene while out to dinner in Los Angeles on Wednesday night.

“He was with a group of friends, but Scott was roaming the venue and bumping into everyone totally wasted,” said the source. “He was guzzling cocktails left and right.”

Disick, 32, who split from long-term girlfriend Kourtney Kardashian in July, appeared to be ready for a rebound as he chatted up eager female fans at the three-hour-long dinner at The Nice Guy in West Hollywood.

“He was conversational and flirty and was acting like a player,” continued the source of Disick, whose antics have been chronicled on the Kardashian family’s E! reality shows.

“When Scott ordered cookies and milk for dessert, he made a suggestive comment to a couple girls at the table.”

The father of three – who spent time in rehab earlier this year after a boozy weekend in Atlantic City — stayed until the last drink was served at 2 a.m. and left the venue with the help of a bodyguard, who led him to a waiting car.

“He was a total mess,” described an eyewitness. “He’s known to drink, but this was taken to a whole new level.”
