Jenny from the Block proved just how far she's come when she kicked off her "All i Have" Las Vegas residency on Wednesday night (January 20).

Following in the footsteps of stars like Mariah CareyBritney Spears and Snoop DoggJennifer Lopez took the Sin City stage with some special help from her famous friends. The former Fly Girl kicked things off with back-to-back performances of “If You Had My Love” and “Love Don’t Cost a Thing” featuring a overboard dance sequence. 

Billboard reported that J-Lo welcomed former collaborator Ja Rule on stage to perform their duet, “I’m Real.” A few songs later, she again wowed the crowd by bringing out Ne-Yo and then Pitbull. The “only in Vegas” show blends Lopez's Bronx roots with props like a bedazzled subway car and sequined Yankees cap. Other fun surprises included a reference to Drake’s “Hotline Bling.”

The stars weren’t only on the stage. In attendance were celebs including Justin Bieber, Leah Remini,Rebel WilsonKelly Osbourne and the  Hoda Kotb from the "Today" show.
