J Lo's ex crawls back out

Jennifer Lopez has filed a lawsuit against her ex-husband Ojani Noa to keep him from revealing all of her "personal secrets" in a new book.

TMZ.com reports that Noa demanded $5 million from Lopez to keep him from selling a tell-all book. The lawsuit states that Noa sent a letter to Lopez's attorney last year, in which he "declared his intention to continue to shop his proposed book and to obtain a publisher for the book."

Lopez's attorneys received another letter from Noa earlier this year, claiming he would not agree to refrain from marketing his book unless Jenny from the block paid him a sum of $5 million.

The lawsuit claims Noa made statements to Page Six alleging Lopez "had an affair with her current husband Marc Anthony while he was still married." Shocker
