The icon's Jennifer Lopez: All I Have opened at The Axis at Planet Hollywood Resort & Casino with a sold-out show. Our girl not only delivered some of her biggest hits ("Love Don't Cost a Thing," "Jenny From the Block," "Get Right"), of course, but also brought out collaborators like Pitbull (for a performance of "On the Floor,") Ja Rule (for "I'm Real") and Ne-Yo (who replaced LL Cool J on "All I Have").

Per E!, the audience in attendance was also full of stars with a guest list that included Justin BieberT.I.Nicole Scherzinger, Ryan Seacrest, Cheryl Burke, Derek Hough, Hoda Kotb, Leah Remini, Gina Rodriguez, Wilmer Valderrama, Rebel Wilson, Ryan Guzman, and the cast of J.Lo's new NBC show, Shades of Blue.

Undoubtedly, January 2016 is J.Lo's month. Not only did she unveil this Las Vegas show, but kicked off the final season of American Idol and saw the premiere of her new show, Shades of Blue, which premiered to strong ratings.
