Earlier in the weekend, Olivia wore Dolce&Gabbana for the Weinstein Pre-Oscar party.

When asked about Brett Ratner shooting a GLAAD video series for LGBT Americans, Olivia shared, “It’s a big honor and big responsibility and I think he’ll do a good job, but if you’re asking me personally, I would’ve liked to see a director who has always been a supporter of the LGBT get this kind of opportunity.”
