The Natalie mention is brief but this article about female role models is a nice read. In it the writer bemoans the fact that Lohan, Spears and Hilton are so prominent.
Speaking of Britney, OK Magazine seem to think Natalie might have seen one of her concerts last week.
And then on Friday night, Fergie and, according to some concert-goers, Natalie Portman, made their way out to New Jersey for the festivities.
Maybe Natalie slipped in and out of LA without anyone noticing but I think its more likely to be a false sighting. Like the time I thought I had a six pack but then realized I was looking at a picture of Brad Pitt at the beach.
