Janet Jackson is planning a tell-all interview about her brother's death.

The 'Together Again' singer has not yet spoken publicly about Michael Jackson's passing but has agreed to speak to America's Harper's Bazaar about her grief.

A source said: "She is giving them the world exclusive and is going to be on the cover."

While Janet has not publicly paid tribute to the 'Thriller' star - who died of acute Propofol intoxication on June 25 - her sister La Toya recently made an emotional posting on her blog.

She wrote: "Michael, after 50 years of waiting, God has finally called you home to do what you do best.

"Mike, you will always be in my dreams! I LOVE YOU SO VERY! VERY! VERY! VERY! MUCH!

"God shared your extraordinary talent with us all for many decades and now it's time for you to spread your wings to a much higher level, which of course I know you will do, and join the other angels and give them an incredible eternal performance. Keep the angels smiling, Joker! I love you deeply and I can't wait to see you perform again!"
