The pretty brunette also showcased her natural beauty by keeping her make-up to an absolute minimum.

Just a few days before her red carpet appearance, the star decided to share her more serious side with fans when she attended the annual Dr. Martin Luther King, Jr. Lecture held at the Zellerbach Theater at Annenberg Center for the Performing Arts.

Clearly moved by what she had heard at the event, Rosario took to her Instagram account afterwards to pay tribute to the African American hero.

The actress admitted that she is still coming to terms with the loss of her beloved grandmother, who passed away back in 2011.

While filming her latest flick Finally Famous, the actress was so cut up that she had to take some tight out to allow herself to mourn.

‘My grandmother passed two years earlier and I had just done so many other projects all over the place,’ she said.

‘I did Trance, I did Sin City, I did '(Cesar) Chavez, I did Gimme Shelter; I worked and worked and worked and I just didn't have time to mourn.

'And I really love my grandmother… I needed to sit and be with my family.
