To look good for when she walks down the aisle, Jessica Simpson went on a detox to shed a few pounds.
But soon after the cleanse was done, Jessica stepped out and dined at Hollywood's Katsuya - a big no-no!
Eating fried rock shrimp, creamy crab rolls, spicy tuna, and crispy rice, Jessica was spotted acting a bit tipsy after taking several sips of sake.
In fact, one eyewitness saw her staggering out and was holding on to her fiancé, Eric Johnson.
Was she drinking TY KU??
Probably would have been a much better choice for Jessica as doctors advice dieters to stay away from rich food and heavy alcohol when they're on a detox cleanse.
Looks like all that hard work went down the drain. Leave it to Jess!
