Margot Robbie Rocks SNL, Supports Marriage Equality

Margot Robbie just hosted the 42nd season premiere of SNL and killed it. If you don't believe me, take a look at this hilarious sketch:

Robbie wore a marriage equality T-shirt while introducing The Weeknd (this past week's musical guest) in support of the effort to legalize gay marriage in Australia. The T-shirt comes from the #SayIDoDownUnder campaign, started by Joshua Sasse (fiance of Kylie Minogue) in partnership with activism group Australians 4 Equality.

"I was shocked to find out earlier this year that same-sex marriage in Australia is still illegal," Sasse wrote. "There are many hurdles to jump in order to make constitutional change, but we are now the closest we've ever been to that change. Let's raise our voice and public support for change. Get a shirt. Wear your heart on your sleeve."

Robbie is fresh off the blockbuster film Suicide Squad, in which she played villain-turned-hero Harley Quinn. She demonstrated her comedic chops on SNL with a hilarious opening monologue, in which she fact-checked herself, and through various impersonations, including a notable one as Ivanka Trump.
