Jennifer Garner picked up a treat from the Prada store in NYC this morning and then changed into a navy dress for a busy afternoon. She fit in a shopping trip before getting started on a string of promotional appearances for The Odd Life of Timothy Green this week. Jennifer stopped by Late Show With David Letterman, where she greeted fans outside and met with the US Olympic women's gymnastics team backstage. She also posed at Sirius XM studios before attending a screening of her film. Her East Coast trip hasn't been just about work, though, since Jennifer was able to meet up with pal Victor Garber at his solo cabaret show. She also has her son, Samuel, to keep her company in the Big Apple. He wasn't by her side this afternoon, however, when she ventured out from her hotel wearing a blue dress.
