Janet Jackson is known for her tight-lipped romances.
But Us Weekly reports that the low-profile singer-turned-actress is officially engaged:
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."
The ceremony will undoubtedly be "a circus," another source says.
The twice-wed Nutrisystem spokeswoman, 46 -- who split from Jermaine Dupri in 2009 -- is eager to make it official with her love of two years.
"She wants kids," says the Jackson source. "If she can't have them, she will adopt."
After a short-lived marriage to James DeBarge in the mid-80s, Janet was married to Rene Elizondo from 1991-2000, but no one even knew about it.
She was most recently with Jermaine Dupri, whom she never married, for most of the 2000s.
Congrats to the happy couple!
