Looks like Melanie Oudin has won over some fans with her astounding U.S. Open run. And when I say "some fans", I means HUGE celebs, like the ones she spent time with at "Fashion's Night Out", an event held throughout N.Y.C. last night celebrating the kick-off of New York Fashion Week. Oudin attended Saks 5th Avenue and Bergdorf Goodman with Anna Wintour, the most influential woman in fashion, and Justin Timberlake, who was showingoff his "William Rast" line. Milk it, Mels, it's just the beginning.
