Margot Robbie hosted the 42nd season premiere of “Saturday Night Live” this weekend and besides spoofing Ivanka Trump, the actress also publicly supported same-sex marriage in her home country of Australia.

The 26-year-old actress wore a T-shirt that read “Say ‘I Do’ Down Under,” above a rainbow-colored map of Australia. The T-shirt is part of Australians 4 Equality, a campaign to legalize same-sex marriage in the country.

The initiative was launched by British actor, and fiancé of Kylie Minogue, Joshua Sasse. Sasse posted a photo of Kelly Ripa wearing the shirt and of himself wearing the shirt next to Dolly Parton on Twitter. The shirts will be available for the public to purchase soon.
