Jessica Simpson Is A Smelly Drunk

Jessica Simpson sang her little Texas heart out in Las Vegas last night, something she has been doing way too much lately. 

The pop country singer, who calls Tony Romo a great boyfriend for putting up with her gassy ass and ABC-belching, got so tanked at the Marc Jacobs Fashion Show afterparty last week that she had to be sent home with the label 'THAT girl.'

While in New York last week, Jessica got so tanked at the Marc Jacobs Fashion Show afterparty that she had to be sent home toting the label 'THAT girl.'  A guest tells Star Magazine:

• 'Jessica was stumbling around the party slurring her words and barely able to stand. It was embarrassing! In New York, it doesn’t matter who you are If you’re acting like a fool, no one will stand for it.'

Jessica, foolish?  Wasn't that to be expected? 

I think the real story is that too many party guests were complaining about the odor of dead cattle after Jessica's ass dilated a few too many inches.  Rose-smelling farts, my ass (pun intended).
