Janet Jackson won’t be performing at her late brother Michael Jackson tribute concerts at London’s O2 Arena in August.

The singer was reportedly lined up to open the gigs at arena, where the King of Pop was due to play 50 dates this summer before his tragic death from an apparent cardiac arrest last month.

However, a rep for Janet has dismissed reports she’ll also appear.

“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,” Contactmusic quoted a family friend as telling MSNBC.com.

Meanwhile, the Jackson brothers; Jermaine, Jackie, Tito and Marlon Jackson will give two special performances, the first of which will be played on Michael’’s birthday on 29 August.
