A Public Affair/Revenge for Jessica Simpson?

Okay, maybe Jessica Simpson isn't THAT mature. After greeting ex-husband, Nick Lachey, with a friendly hug last week, Jess went on TRL yesterday and premiered her new video for "A Public Affair."

Sadly, Vanessa Minnillo - Lachey's current squeeze - wasn't hosting the program, leaving viewers without any enjoyable, violent cat fight. But when the video finally came on - involving Simpson skating around with gal pals, Christina Applegate and Eva Longoria - there appeared to be a direct slam at Minnillo.

While she's lacing up her boots, Jessica spots a hunky dark-haired stranger canoodling with a brunette; this supposed slut then has an aggressive fantasy focused on yanking out Simpson's hair in a fit of jealousy.

And just who plays this female foe? A TV entertainment reporter named Maria Menounos.

We're not sure if Jessica is trying for any real-life metahpors here, but if she is - well, we're confused. Didn't Simpson divorce Lachey?
