A kung fu fighter in a disco

In the US, at least, I think people take J-Lo quite seriously on both fronts. Somehow she managed to do the "In fact I always *wanted* to become a singer, the acting thing just broke for me." story believably. And although she's become incredibly tiresome after several years on the publicity circuit (anyone remember those stories about her 4ss being insured?) her first two albums were taken pretty seriously, certainly on a completely different level than Madonna ever received.
