Billboard -- Janet Jackson has found someone to call her fiancee: the R&B/pop superstar is reportedly engaged to her longtime boyfriend, Qatari billionaire Wissam Al Mana. According to Us Weekly, Jackson and her fabulously wealthy beau are planning to trade vows in spring 2013, after the singer was given a ring earlier this year. Al Mana, a 37-year-old Middle East investor, has been dating Jackson since 2010. Jackson, 46, was previously married to James DeBarge and Rene Elizondo, Jr. She split from hip-hop mogul Jermaine Dupri in 2009. In 2012, Jackson became a spokesperson for Nutrisystem, and considered joining the judges panel on the U.S. version of "The X Factor" before eventually turning down the gig. Earlier this month, the singer and amfAR ambassador co-penned a CNN op-ed along with the AIDS research foundation's founding chair Mathilde Krim in honor of World AIDS Day.
