Scott Disick poured vodka over a group of college students on Monday night (02.12.13).
The 'Keeping Up with the Kardashians' star, who has frequently argued with his long-term girlfriend, Kourtney Kardashian, about his drinking on the reality TV series in the past, reportedly caused ''chaos'' when he partied with the brunette beauty at her former college, the University of Arizona in Tucson.
A source told gossip website RadarOnline.com: ''You wouldn't believe the madness that went on last night. The students were ecstatic and it was complete chaos.''
The 30-year-old star was spotted pouring alcohol from an upper terrace at Gentle Ben's pub and cameras captured the entire incident for the couple's E! reality show.
An insider recently told Life & Style magazine that Scott, who has a son, Mason, three, and 18-month-old daughter, Penelope, with Kourtney, has allegedly been partying more since the death of his mother, Bonnie, from cirrhosis of the liver in October.
The source said: ''Scott is devastated. Kourtney sees him heading down a bad path again. She's trying to help him through this [and] giving him the sympathy he needs.''
