The wait is over.
After months of preparations, Jennifer Lopez kicked off her headlining Las Vegas residency, Jennifer Lopez: All I Have, at The AXIS at Planet Hollywood Resort & Casino Wednesday night. The "Waiting for Tonight" singer, 46, brought out a few surprise collaborators, including Ja Rule ("I'm Real"), Ne-Yo ("All I Have") and Pitbull ("On the Floor"). The pop superstar performed for a sold-out, star-studded crowd that included Justin Bieber, Cheryl Burke, Derek Hough, Rosie Huntington-Whiteley, Hoda Kotb, Leah Remini, Gina Rodriguez, Nicole Scherzinger, T.I. Wilmer Valderrama and Rebel Wilson. Other supporters included her American Idol colleague Ryan Seacrest, her Boy Next Door co-star Ryan Guzman, and her entire Shades of Blue family, including Santino Fontana, Sarah Jeffery, Warren Kole, Ray Liotta, Dayo Okeniyi and Gino Pesi.
The audience danced along with Lopez as she sang her biggest hits, including "Love Don't Cost a Thing," "Jenny From the Block" and "Get Right." The show was directed by Napoleon Dumo and Tabitha Dumo (aka Nappytabs) and was supported by a live five-piece band and 16 dancers.
Lopez's boyfriend, choreographer Casper Smart, knew fans wouldn't be disappointed. "It's everything you can expect and more. It is so entertaining," the 28-year-old said on the red carpet before the concert began. "I can't even...It's just entertainment from start to finish."
