Anna Kournikova Hauls Tons of Booze Out of Costco

Anna Kournikova's all about that top-shelf life -- blame it on the Goose -- during a recent trip to the grocery store.

The former tennis superstar was leaving Costco Wednesday in Miami, and she loaded up with groceries and TONS of booze. How big a haul are we talking here? She needed help from 3 assistants to get her car loaded.

But, it's hard not to miss her cart ... loaded with 6 Ketel One bottles, 4 Grey Goose bottles, a bottle of Patron and champagne. Why the liquor haul? We don't know for sure, but Anna and Enrique Iglesias' twins are turning 1 in just a few days.

The kids might not know it's a party but -- from the looks of it -- the adults definitely will. Bottoms up!
