J.Lo launches 'All I Have' preview show + Casper Smart scorns fans for sharing footage...

Jennifer Lopez launched her Las Vegas residency 'All I Have' at Planet Hollywood with a preview show for family and friends last night.
The high octane show officially kicks off tomorrow night. More footage out there shows that her sets are not too elaborate, and the choreography hasn't been switched up too much from her recent concerts. Jen's boyfriend Casper Smart is pissed that some of the videos are out and berated a user for uploading. "You were instructed and asked not to post this video till wed night!!!" he scorned.
