Jennifer wraps her world tour with Enrique Iglesias this weekend in Miami and Orlando, so the singer is probably looking forward to some rest and relaxation on Labor Day.

While she backed out of hosting another season of American Idol, J.Lo will be plenty busy working on other projects. It was announced earlier this week that ABC Family greenlit a pilot produced by Jennifer centering around a lesbain couple and band of adopted multi-ethnic kids.
