Ashley Olsen stepped out of her NYC apartment carrying her adorable French bulldog yesterday. Ashley has been out and about in the Big Apple as she and Mary-Kate prepare to launch their most recent Olsen line for Stylemint. The shopping website, which Ashley and Mary-Kate are starting together, is set to debut this Friday and will include an eight-piece t-shirt collection designed by the duo. The venture is a collaboration with the company that launched Kate Bosworth and Cher Coulter's JewelMint and is also coming out with BeachMint. Mary-Kate and Ashley's exciting new project comes on the heels of their 25th birthday, which they celebrated earlier this month.
