Anthony took the stage first, singing mostly his Spanish hits and telling the audience, "I missed you guys. This is a special night for us on so many levels."

After nearly 90 minutes, Lopez came onstage wearing a flowing baby doll top and flared bottoms by Roberto Cavalli. She opened with her new single "Do It Well," and showed off some low-key hip-hop dance moves.

A few songs into her set, a breathless Lopez asked the crowd, "How amazing is Marc?" She added: "This is a really special night for us ... This is my first tour ever! It's been a really special year."
