For her husband MARC ANTHONY's 38th birthday, JENNIFER LOPEZ led a love train across Las Vegas Sept. 16. First stop: Caesars Palace, where the couple jammed to JUAN GABRIEL in concert. Next: Tao at the Venetian, where 25 guests, including LEAH REMINI, gathered for an Asian-themed feast. After dinner, Lopez—who opted for dancing over drinking—treated her Coors Light-sipping husband to a group performance of the Jackson 5's "I Want You Back." The singer even led a conga line and kissed Anthony in full view of partygoers. "They were close the whole night," an observer tells Insider. Adds guest DJ SWIZZ BEATZ: "They're a natural match."
