I’ve been dying for someone to wearing a look from Stella McCartney’s Spring 2010 collection, and that honour went to Natalie Portman.

The actress was on the show to promote her new movie “Brothers” also starring Tobey Maguire and Jake Gyllenhaal, which hits theater’s December 4.

Letterman called it “The finest movie made in the last 12, 20 years”, in fact he gushed non stop about the movie during her interview.

Natalie is radiant in her strapless blue mini Stella McCartney Spring 2010 button down dress, with fold detail on the neckline and an A-line skirt.

Her hair is swept to one-side with a jeweled clip decorating her hair, plus she wears her dress with the same purple Aldo heels which she wore with her blue Jason Wu dress.

Unfortunately the screen-grab isn’t doing this dress any justice, so please view the you tube video below.

I WISH this was worn on the red carpet, it has to be one of her best ever looks and Natalie has had plenty of fine moments.

Now I’m the one gushing.
