Don’t mess with Tony P!!

Tony Parker is suing X17 for $20 million over the allegations that he cheated on his stunning wife Eva Longoria with French model Alexandra Paressant in an affair that went on for months.

TMZ has obtained a copy of the lawsuit, filed today in L.A., which claims “X17 had to know that the story was false, or at the very least, it had to have entertained serious doubts about the credibility of its supposed source.”

Parker claims the photo agency never attempted to verify the rumor and ran the story regardless.
