Jennifer Lopez boarded her private jet last night to leave Paris and return to Portugal, where she'll resume the European leg of her Dance Again world tour Friday. J Lo was in Paris for just one day to take part in some Fashion Week fun. Jennifer brought her daughter, Emme, to Chanel, and later thanked the house's designer for allowing them to go. J Lo tweeted, "Thank You Karl Lagerfeld for inviting Emme and me to her first fashion show! It will always be our memory of our first fashion show together." The little one stayed at home for last night's Valentino event, which Jennifer attended with Casper Smart. Emme's twin brother, Max Anthony, also went along for the French fun, but skipped all the PFW events.
