Photos of Natalie Portman at the Tribeca Film Festival

Natalie Portman has been helping kick off the Tribeca Film Festival including stopping by the portrait studio earlier today. On Tuesday she made an appearance at the Film Fellows welcome dinner to preview a new website she's been working on called MakingOf.com, which shows the workings of the entertainment industry from the inside out. Between the events was Earth Day, which is big for one of our 15 favorite eco-loving celebs. Meanwhile, apparently Natalie has also been finding time to be a friend to Lindsay Lohan, which the troubled startlet eagerly pointed out during her interview with Ellen.
