Blake Lively spoke at the White House on Friday (08.11.13).

The 26-year-old actress, who is married to 'The Proposal' star Ryan Reynolds, was invited by U.S. first lady Michelle Obama to appear on a star-studded panel alongside film producer Harvey Weinstein, 'The View' host Whoppi Goldberg and 'Skyfall' star Naomie Harris for a Careers In Film Symposium workshop.

The former 'Gossip Girl' star helped to educate a group of high school students visiting Washington D.C. from New York and Boston about what it is like to work in the movie industry, according to EOnline.com.

The blonde beauty looked stunning in an unusual black dress and minimal make-up.

Blake recently confessed she doesn't need to do much to look good and eats chocolate every day.

She said: ''I do nothing! I'm lucky to have a very active lifestyle, I'm always running around everywhere... So I don't need to hire a coach or watch what I eat. I can't start my day off without a mug of hot chocolate or finishing off the day with a few squares of dark chocolate... It keeps me feeling happy.''
