One's won an Oscar and the other's bound to get one! In addition to their on screen sucess, both Marcia Gay Harden and Natalie Portman succeeded on the red carpet of last Friday's American Cinematheque Awards in Beverly Hills.

Looks like this "Into the Wild" star has been into the gym lately, looking so so not 40-something in this David Meister satin gown.

But then again, she's always been a pretty fly momma (literally, she's a momma of 3).

To 2006 Miss Universe Zuleyka Rivera (l, above): As bright as your dress is, you're still being outshined by the lovely Harden. Take notes (20 years worth).

Back in Beverly Hills:

Natalie Portman also went ga-ga for a gown in a purple hue, opting for a simple yet elegant form-fitting satin strapless.

I don't know about that little sack thing as an accessory...

...but it's good to know Portman is bringing classy back to the young Hollywood set (once again, take notes!).
