Scott Disick played a bit too hard Saturday in Atlantic City. Witnesses say Kourtney Kardashian’s smarmy baby-daddy was vomiting in a garbage can after an afternoon at the Pool at Harrah’s Resort. We’re told Disick ordered shots and Heinekens from noon to 5 p.m. and a Caesar salad for lunch. “Probably not the best combo,” quipped a source. Disick’s rep had no comment. While he partied, Kourtney had a baby shower in LA for her second child with Scott.
