Full set: Jennifer Lopez's iHeartRadio music festival performance...

Last night saw Jennifer Lopez giving fans a taster of what to expect from her upcoming residency in Las Vegas (beginning January 20th.) She announced exclusively during her set at the iHeartRadio music festival that the residency will be called 'All I Have.'
Sporting braided hair and a custom Bao Tranchi bodysuit, the singer shook what her mama gave her performing five songs, including a medley of some of her biggest hits. I have no doubt in my mind that her residency would be one of the hottest tickets in town. 

As seen in this performance, J.Lo certainly goes out of her way to put on a show. Britney Spears and Mariah Carey are also doing residencies in Las Vegas and people aren't really getting from the artist what made them so appealing. Mariah can't sing like she use to and Britney's dancing leaves little to be desired. But at least with J.Lo, you're still going to get the high octane showing and intricate choreography she's been admired for her entire career. Check out her entire set below.
