Jennifer Lopez touched down at the airport in Nice, France, this morning with her daughter, Emme, in her arms. J Lo is back in Europe after a quick jaunt to the US for Monday's Costume Institute Gala, where she ranked among Fab's best dressed of the evening with her Zuhair Murad gown. Jennifer and her kids had previously been in Spain and England as she promoted The Back-up Plan. The Lopez-Anthony family is back in the Mediterranean area, just a couple months early for their annual yacht and bikini vacation with friends Dolce and Gabbana.
