“Gossip Girl” star Kelly Rutherford has a new place on the Upper East Side. The pretty blonde — who traveled to France more than 40 times in the past year to visit her kids after losing a costly custody battle against her ex, Daniel Giersch, which forced her to declare bankruptcy — tells us her old lease was up. “I’ve moved so many times in my life, it’s actually purifying,” she said. “I love going through my closets and cleaning things. Every time you move, you do weed out a lot of stuff.” Rutherford also says she’s decorating on a budget: “I’ve taken a lot of trips to Ikea. I like the clean lines, I like the simpleness of it. CB2, all that stuff. I mix it with other things.”
