When we caught up with Mischa Barton at the Whitney Museum of American Art's gala this week, we asked if she had artistic aspirations beyond just acting. "Well, we have paint parties at my house, and everyone comes over and paints on blank canvases, and just does things for fun," she told us. "My kind of art has always been film. That’s my primary interest, and everything else is just a hobby." See more in our Party Lines slideshow.
