Scott Disick may think of himself as a Lord, but there’s another L word people are starting to associate just as much with the Keeping Up With the Kardashians star: lush.

A source confesses to Star  (via RadarOnline.com) that the father of two was living it up during Cinco de Mayo festivities at the Hard Rock Hotel Riviera Maya in Mexico and having a few too many libations in the process.

Scott was reportedly rolling deep that night, with a gaggle of hot girls, as well as his usual crowd of hangers-on, in tow.

The eyewitness says that, despite the party atmosphere, Scott was “in a remote corner of the resort, drinking himself into a stupor” and seemed to be in a foul mood.

Another partier claims that, when she went up to Scott to ask for his autograph, he looked worse for wear — but managed to hit on her, anyway.

Describing Scott as bleary-eyed and “sweating like crazy,” the woman says that Scott became enraged when she made a joke about him being intoxicated and staggered away from the party to sit on the beach by himself.

Scott’s drinking has been an issue for girlfriend Kourtney Kardashian in the past, so it looks like the Lord may have to break up with the bottle before Kourtney breaks up with him.

Do you think Scott is getting too old for his hard-partying ways?
