Mischa Barton cut loose in the mountains on New Year’s Eve. The star was spotted at an opening for hip ski lodge Wildwood Snowmass, with guests Karenna Gore Schiff and Coralie Charriol Paul. “Mischa was chilling with a guy who seemed like a flirty friend,” said a spy. Decked out in a black-and-white top with cutouts and paper top hat, “She seemed in high spirits, dancing enthusiastically to tunes by DJ Kid America.” Al Gore and Katie Couric were also spotted by Snowmass snoops.
