Jennifer Lopez Opens Vegas ‘Up All Night Live’ With Ja Rule Surprise and 120-Minute Revue

The limited, second residency runs through March 28, 2026 at The Colosseum, showcasing reworked hits backed by a 15-piece orchestra.

Overview

  • Lopez launched the engagement on Dec. 30 before a sold-out crowd of more than 4,000 at The Colosseum at Caesars Palace.
  • The roughly 120-minute, four-act production reframes her catalog with Broadway and jazz covers, theatrical set pieces, and fresh arrangements.
  • Ja Rule made an unannounced appearance to perform early-aughts favorites “I’m Real” and “Ain’t It Funny” with Lopez.
  • Addressing commentary about her wardrobe, Lopez told the crowd, “If you had this booty, you’d be naked too.”
  • The premiere featured frequent costume changes curated by Rob Zangardi and Mariel Haenn, including a sheer spiderweb lace catsuit, a tuxedo-inspired bodysuit, and sequined gowns.
