Mischa Barton says she’s staying in New York even though her show, “The Beautiful Life,” got canned. At the Sony Vaio launch at Guastavino, Barton said, “I grew up in the city, so there’s a lot to love about it. All my close friends are here. I feel it’s a fun city to lay low in and you get treated right.” About her next career move, she said, “There’s a bunch of projects I always wanted to make, so I’m going back to thinking about things again. I just started looking at films.”
