Actress Blanca is known for her role in Teen Star Academy, Bullet and Bermuda Tentacles.

The stars were out in force tonight for Hollywood's biggest night of the year, with actress Jessica Biel leading the best-dressed.

The actress appeared to take inspiration from the highly-coveted golden statue as she hit the red carpet in a striking gold dress which insured she stood out from the crowd of A-listers.

But on the other end of the spectrum, everyone from Dakota Johnson to Leslie Mann led the worst dressed on the red carpet, falling short in the style stakes.

Elsewhere, Oscar nominee Taraji P. Henson kept classic with a black velvet Alberta Ferretti gown.
