Usher has left behind a life of making love in this club to become a card-carrying member of the happily wedded club. The R&B star, 36, got hitched to longtime love Grace Miguel in a private ceremony earlier this summer, E! Online reports. The newlyweds, who've been engaged since January, reportedly honeymooned in Habana, Cuba, over Labor Day weekend. Speculation about the nuptials has been buzzing since last week, when Miguel, 44, posted a shot of the lovebirds on Instagram showing her boo wearing a gold wedding band. E! has confirmed that the couple filed their marriage certificate with their local county court in Georgia this month. Not only have the pair have been dating for six years — Miguel also manages the Grammy-winner's career. Mixing love and work can be tricky, but it seems the couple's business relationship is working proof that they trust each other and work well hand in hand. In an interview with Billboard in 2014, Usher called Miguel "an incredible partner and manager," saying "She helped me through some of the hardest times in my life and my career."
