Thirty-seven year old Al Mana, who hails from Qatar, is reported to have proposed to Ms Jackson a few months ago but news is only just seeping out about the forthcoming wedding.
Indeed, a source told US Weekly that the millionaire investor gave Ms Jackson  a “huge, expensive ring” earlier this year but the Together Again singer was afraid of losing it and kept it hidden away.
The source explained: “She’s afraid it will get lost, so she keeps it locked up!
“He is flying all of Janet’s friends and family on private jets. He wants to get a top chef to create a custom menu.”
Ms Jackson has been married twice before, to singer James DeBarge and Rene Elizondo Jr while she split from hip-hop producer Jermaine Dupri in 2009.
