Kim Kardashian prides herself on never getting drunk ... but on last night's episode of "Kourtney & Kim Take Miami," she got obliterated.

Filmed before the reality star got pregnant, Sunday's show was filled with clips of Kim and her sister Khloe boozing up and hitting the town.

With Scott Disick as their designated driver, the two were as giggly and loud as most after having a few too many.

At one point, Kim was even seen drinking Midori right out of the bottle. Of course, the company pays her to be the face of the liqueur ... they must be loving the free promotion.

Check out the clip above to see their wild night out.

And while Kim may not be drinking anymore now that she's preggers, she is still hitting the club scene. Click here to see photos of her at a nightclub this weekend in Africa!
