Tipsy Jessica Simpson Stumbles Out of Husband’s Birthday Party

Jessica Simpson sure had a great time celebrating Eric Johnson’s 38th birthday!

The 37-year-old singer had so much fun with her husband that she had to be helped out of Craig’s Tuesday night following a 5-hour dinner. Stumbling out of the fancy West Hollywood restaurant, she nearly fell off the sidewalk while making her way to her car.

Via TMZ:

Luckily, her hubby and a pap were there to avert disaster. We asked Jess what’s her secret to a perfect butt pic … ’cause she would know.
