Janet won't sing at Jackson birthday tribute

LOS ANGELES: Janet Jackson has dismissed reports she will appear as a surprise guest at tribute concerts to mark her late brother Michael Jackson's birthday in August (09).

The star was reportedly lined up to open the gigs at London's o2 Arena, where the King of Pop was due to play 50 dates this summer before his tragic death from a cardiac arrest last month (Jun09).

The Jackson brothers; Jermaine, Jackie, Tito and Marlon Jackson will celebrate the Thriller hitmaker with two special performances, the first of which will be played on Michael's birthday on 29 August (09).

However a representative for Janet has brushed off suggestions the singer will also appear, insisting the concerts aren't "about her".

A family friend tells MSNBC.com, "Janet has plenty going on as it is - she’s filming a movie (Why Did I Get Married Too) and she’s involved in Michael’s kids’ lives. These concerts are not about her and she respects that. She’s always been independent.”
