Is Janet Jackson getting married? That’s the question on everyone’s minds after the National Enquirer published a report suggesting that the R&B/Pop star is now engaged to her billionaire boyfriend Wissam Al Mana.

According to the National Enquirer’s story, Wissam, a Qatari businessman, recently popped the question, and now the happy couple is planning a wedding that will take place at the end of the year.

“Janet is head over heels in love with Wissam,” a close source said. “He’s showered her with love, expensive presents and boosted her self-esteem by helping her lose weight and shape up.”

Last fall, Wissam, with a 15 carat diamond ring in hand, reportedly asked Janet to marry him. However, the 45-year-old entertainer wasn’t ready to make the big leap just yet and turned it down, as she was focusing on preparations for a tour, which runs into September.

“Now Janet’s telling friends that an official engage­ment announcement will come by summer’s end, and that she and Wissam will marry in late 2011 – and they’re shopping for an even bigger diamond ring to celebrate their official engagement,” the source continued.

The source also revealed that Janet and Wissam are “anxious” to start a family ASAP, whether it be through natural childbirth or adoption, because at 45 years old, Janet’s chances at having her own child are getting slimmer and slimmer.

Janet Jackson was previously married to singer James DeBarge in 1984, but they annulled their union after only one year. Her next marriage — a secret one — was with dancer/video director Rene Elizondo, which lasted 9 years, ending in 2000.

Then she got into an 8-year relationship with rapper/producer Jermaine Dupri that never developed into marriage, and ended in 2009, which is the year she met her current boyfriend Wissam Al Mana.

“Janet says she’s finally found her knight in shining armor!” the source said, regarding Janet’s newest relationship.

Congrats to Janet and Wissam (if this is all true)!
