A representative for Janet Jackson has denied speculation that the singer will perform at her brother Michael Jackson tribute concert. Furthermore, her friend has also told New York Post about her exclusion from the gig, "Janet has plenty going on as it is - she's filming a movie ('Why Did I Get Married Too?' in Atlanta) and she's involved in Michael's kids' lives. These concerts are not about her and she respects that."

Beside Janet Jackson, other stars who have been rumored to sing at the tribute concert are Justin Timberlake, Jackie Jackson, Tito Jackson, Jermaine Jackson and Marlon Jackson. While Janet has slammed down the rumor of her involvement in the project, Justin and the four remaining members of Jackson Five haven't given any word on that matter.

AEG is expected to hold the tribute concert either on August 29 to mark Michael's 51st birthday or sometime in September. The gig reportedly will take place at London's O2 Arena where Michael was supposed to hold his "This Is It" gig with "the brothers performing, some sisters, and the stars that were influenced by him."

Most recently, Michael Jackson's rehearsal footage for the canceled concert may be turned into a feature film with Sony Pictures in final talks to obtain the rights for the untitled Michael Jackson project. The movie is tentatively scheduled to arrive in theaters on October 30, and Kenny Ortega will possibly be tapped for helming job. As for its TV project, reports in the media revealed that the deal between AEG and NBC has reached a dead end. Other networks have also lost interest to secure the deal.
