Jennifer Lopez wears some absolutely fantastic things, but the singer and American Idol judge is not what I would call the arbiter of good taste: she likes her clothes short, spangly, and as skintight as she can manage without bursting a blood vessel. I mean, can you blame her? This week, J.Lo brought boytoy Casper Smart (who, ugh, I just noticed has a neck tattoo) along for the ride to celebrate the launch of her new single in Vegas, and I don’t think the term “minidress” does the teeny-tiny garment she chose for the occasion justice. Of course it looks fabulous on her — duh, it’s J.Lo — and it is Vegas, but I can’t look at her in this dress without wincing. How often do you think she had to pull that shit down lest she flaunt the fallopians? Jenny from the block needs a sit-down talk about not show-cha(ing) her chocha.
