According to US Weekly......
A source tells Us Weekly that Qatari billionaire Wissam Al Mana "gave her a huge, expensive ring" earlier this year.
"She's afraid it will get lost, so she keeps it locked up!"
The luxury-brand mogul, 37, will spare no expense on his nuptials to Miss Jackson, set for spring in Qatar.
The affair "will cost millions," reveals a second Jackson insider. "He is flying in all of Janet's friends and family on private jets." (Quick refresher: The L.A.-based singer has seven siblings and more than 20 nieces and nephews.)
Adds the source, "He wants to get a top chef to create a custom menu.
Since this is not the first time rumours of her supposed engagement broke out this year, I'll keep my fingers crossed for this one.
