Jennifer Lopez did a quick change in Paris today, slipping out of the little white dress she wore to this morning's Chanel show and into a flirty pink dress to check out Valentino. J Lo brought her daughter, Emme, and boyfriend, Casper Smart, along to see Chanel, though for Valentino's midday Paris Fashion Week presentation, she arrived holding hands with just Casper. The pair sat in the front row, next to the designer himself, and got a close look at the Spring 2013 Valentino designs as they came down the runway. Afterward, J Lo returned to her hotel to pick up her son, Max. J Lo and her gang are currently touring Europe as part of her Dance Again world tour. Following their quick stop in France, they're jetting back to Portugal for a show in Lisbon before moving on to Spain, Ireland, Russia, the UK, and Turkey.
