We've been fans of Katie Holmes since way back in her Joey Potter days, so we get a little thrill when we see just how far she's come in the style stakes. Fronting Ann Taylor's Spring 2011 campaign, Holmes looks downright stunning in the label's new collection, which melds sportswear and sophistication to create covetable day-to-night looks we can't wait to get our hands on. Shot by Tom Munro, the campaign will hit mags in March, but lucky for you we've got a sneak peek. Check out this behind-the-scenes pic and see for yourself! (People)
