Jessica Simpson JSIMPSONTROMO120107_01.jpg OK! Magazine's report that Tony Romo had unceremoniously dumped Jessica Simpson must have been music to the ears of bitter Cowboys fans everywhere - but Jess says that it's all BS!

The blonde bombshell's lawyers fired off an angry letter to OK's editor-in-chief calling their news item a "defamatory and gratuitously mean-spirited article" and demanding that the magazine cease its "scurrilous" attacks on her, PageSix.com reports.

Jessica also took the opportunity to reaffirm her love for her sister, whom OK! had claimed had grown distant from Jess recently.

OK!, however, is sticking to their story - as of right now, their article is still viewable on their site.

Looks like this one may come down to the ref's call!
