When has JLo ever displayed "shady" behavior towards Mariah? It's always been Mariah doing that to her. I believe JLo's a genuine Mariah fan. She was there cheering when Mariah got the Billboard Artist of the Decade award. And her first single (and general musical direction) was obviously highly influenced by what Mariah had been doing around that time. You know what they say about imitation being the greatest form of flattery. But to make it look like she was instrumental in all that sample stealing issue gives her too much credit in the songwriting and production of her own music. I agree that it was all Tommy. She most probably wasn't even aware of what was happening until Mariah brought it up.
