Jennifer Lopez is prepping her appearance at the AMAs this Sunday, in a spectacle that will involve a boxing ring, fireworks and an on-stage costume change, reports The AP.

But while she's planning on revealing her new single at the Nokia Theatre, her attorneys are trying to keep a decade-old sex tape from surfacing in the trial against her ex-husband, Ojani Noa.

Lopez got a temporary restraining order that prevent Noa from going ahead with his planned "mockumentary," How I Married Jennifer Lopez: The J.Lo and Ojani Noa Story, which uses footage taken during the couples' honeymoon.

Lopez successfully blocked Noa from writing a tell-all book five years ago, because it violated the terms of their divorce settlement. Now, she's suing him for 10 million for "shame" and "humiliation" over his latest attempt to make money off their one-year marriage, but that court case, which was scheduled for this morning, may cause Lopez more grief than good!

Noa's manager, Ed Meyer, issued the following statement:

    For the third time, Jay Lavely, Esq. of Lavely & Singer, has postponed the Ex-Parte hearings on behalf of his client Jennifer Lopez. The Ex-Parte hearing scheduled for tomorrow, Friday, November 20, 2009, has been withdrawn by Mr. Lavely. The issue at hand is that Mr. Lavely realizes that I have the right to introduce the Jennifer Lopez "Sex Tape" as evidence into full public record, so Jennifer Lopez and her attorneys are stalling for time. Especially, with her upcoming performance at the American Music Awards on ABC on Sunday night. I will advise all when the next hearing is scheduled.

Seems like Ojani's not going down without a fight!
