Janet Jackson: Engaged to Wissam Al Mana (Reportedly)!

After two and a half years of dating, Wissam Al Mana and Janet Jackson are engaged, according to a new report - and they're planning a secret wedding to boot!

Wissam Al Mana "gave her a huge, expensive ring" earlier this year, Us Weekly claims. So big, in fact, "She's afraid it will get lost, so she keeps it locked up!"

The luxury-brand mogul, 37, spares no expense when it comes to the 46-year-old sister of Michael Jackson. Insiders say they'll wed in spring in his native Qatar.

The wedding "will cost millions," reveals a Jackson insider to the celebrity magazine. "He is flying in all of Janet's friends and family on private jets."

That would be ... pricey. Janet Jackson, of course, has seven siblings and more than 20 nieces and nephews, plus her parents Joe and Katherine Jackson.

And that's not all. 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.

While the private Janet has yet to confirm the big news personally, she is said to be over the moon about the wedding, and starting a family with Wissam Al Mana.

"She wants kids," says the Jackson source. "If she can't have them, she will adopt."

Congratulations to Janet and Wissam - if in fact this piece of celebrity news is true!
