NFL Star Jeremy Shockey's Wife -- You Posted My Naked Pic ... And NOW YOU'LL PAY

NFL star Jeremy Shockey's extremely hot estranged wife is up in arms over her naked backside -- claiming the Super Bowl champ posted a photo of her bare butt on the Internet ... and now, she wants him to pay.

Daniela Cortazar-Shockey -- who married Jeremy last May before the couple separated in October -- just filed legal docs contesting their prenup.

Despite the agreement -- which leaves her with zilch in the event of a divorce -- Daniela claims she's still entitled to temporary alimony and lawyers' fees under Florida law.

But the interesting part, Daniela is also demanding at least $15,000 from Jeremy, claiming he violated a privacy provision in the prenup by posting a picture of Daniela's butt on Instagram recently ... long after they split up.

The picture has since been removed from Jeremy's social networking accounts.

Daniela is also asking the court to force Jeremy to stop posting about her on the Internet.
