Jennifer Lopez and Marc Anthony may have gotten up close and personal for just one night, but it was purely professional. The two estranged exes, who are currently going through a divorce, came together for Q'Viva! The Chosen Live concert over the weekend. Q'Viva was a project that Lopez and Anthony teamed up for prior to their very public break-up last summer. But in Hollywood, the show must go on. Despite an acrimonious split this past July, the couple made beautiful music together as part of the event that showcased their global talent competition. Both musicians put on quite a show for the sold-out show in Las Vegas. According to Usmagazine.com, the couple stood close to each other and held hands. Before leaving the stage, they even gave each other a tight embrace. Although 42-year-old Lopez and 43-year-old Anthony were hitched for seven years and have two children between them, don't expect a reunion. Lopez has been shacking up with boy toy and back-up dancer Casper Smart, while Anthony has been dating Venezuelan model Shannon de Lima.
