Janet Jackson secretly engaged to Qatari billionaire Wissam Al Mana

Janet Jackson has reportedly become engaged to Qatari billionaire Wissam Al Mana, whom she's been dating since 2010.

The 37-year-old businessman gave her a huge expensive ring and the 46-year-old pop star is so afraid it will get lost, she keeps it locked up  according to Us Weekly.

Wissam is the managing director of Al Mana Retail, which represents A/X Armani Exchange, and he's a shareholder in the Saks Fifth Avenue.

Janet's wealthy beau plans on sparing no expense for their spring nuptials in Qatar, and 'he s flying in all of Janet's friends and family on private jets.'

One source said that the pair's ceremony will undoubtedly be 'a circus,' and Al Mana plans to hire a 'top chef to create a custom menu.'

The Miss You Much hitmaker, who's almost a decade older than her Middle Eastern man, wants to start a family as soon as possible.
