Did it really help J.Lo though? I mean, in any sort of truly significant way? It may have brought her "back" a little but I honestly had no idea she even had a single in the last 5 years and I used to be on top of her music. And as for Adam Levine, Maroon 5 wasn't really old news at that point. They were still somewhat relevant when he did that show so it didn't seem like a desperate attempt to reclaim popularity.
