The singer is said to have become engaged during the Christmas holiday, to Qatari billionaire Wissam Al Mana, whom she's been dating since 2010.

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

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. Janet's wealthy beau plans on sparing no expense for their spring nuptials in Qatar, and 'he is 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. 'If she can't have them, she will adopt,' said a Jackson insider.

The Nutrisystem spokesperson was last seen with the luxury-brand mogul shopping in West Hollywood earlier this month, and in July the loved-up couple were spotted laughing on a yacht in Sardinia.

Janet, who's net worth is estimated at $150 million, has been married twice before.

In 1985, she had her marriage to childhood friend and singer James DeBarge annulled after eloping only months earlier. And in 1991, she secretly married dancer, songwriter, and director René Elizondo, Jr., but the longtime couple divorced in 2000. Two years later, the Rhythm Nation songstress began her on/off seven-year relationship with record producer Jermaine Dupri. In the past, Jackson was linked to actor Rob Lowe, Hollywood screenwriter Gary DeVore, rapper Q-Tip, actor Matthew McConaughey, and Boyz II Men's Wanya Morris.

Miley Cyrus has gotten engaged to "Hunger Games" star Liam Hemsworth, People is reporting.

Cyrus, 19, has been dating Hemsworth, 22, for three years, and the engagement has been confirmed to the magazine by their representatives. A wedding date has not yet been set.

"I'm so happy to be engaged and look forward to a life of happiness with Liam," said the singer/actress.

Australian actor Hemsworth and Cyrus met when they shared screen credits in 2009's "The Last Song." People reports that he proposed on May 31 with a 3.5-carat diamond ring in a gold band.

As People's Julie Jordan told TODAY on Wednesday, "It's kind of sweet, because they shared Miley's first on-screen kiss together. They've been together since she was 16. They have a very playful relationship. Very real. Very honest."

Added Jordan, "I think Miley has obviously gotten a good dose of what fame and fortune is like, and now with Liam coming into his own.... She's very excited about his success, and I think they're going to be good for each other. They're definitely going to keep each other balanced."
