Rumors have been swirling all week about Aerin Lauder possibly departing the family business. Today, the details have been released. Aerin, the granddaughter of Estée Lauder, is launching her own lifestyle brand. Aptly called Aerin, the luxury lifestyle brand will include a beauty collection to be sold at select Estée Lauder counters beginning in 2012. She'll continue to serve as an Estée Lauder global brand ambassador and spokesperson while developing her own brand. Judging by her favorite spots in Paris, expect nothing but high style and impeccable taste.
