Natalie Portman is seen getting into her car after spending time at an office building in Los Angeles.

Natalie’s been in the news today with rumours of her and Sean Penn ‘hooking up’ at the Sunset Towers in Los Angeles.  According to an eyewitness that told the Star:

“I had to go through some curtains — and that’s when I interrupted Sean and Natalie!” the source reports. “When they saw me, they were startled and quickly composed themselves.”

We all know Sean Penn’s reputation for his douchebagging antics, but I will not believe that Natalie Portman would ever do such a thing.  I can just imagine the things the pappers were saying and asking her given the timing.

What do you think?
