The couple tied the knot in an intimate ceremony on December 23. Media outlets picking up the news after their friend Conrad Carr posted Instagram stories of the pair cutting a wedding cake.
The pair later confirmed the news on their own Instagram pages, posting an image of themselves embracing. Cyrus also revealed that her ivory off-the-shoulder gown was created by top designer Vivienne Westwood.
She captioned an image of the couple kissing: "This is probably our one - millionth kiss ...." Another image was captioned with their wedding date: "12.23.18." Hemsworth shared the same picture, which was simply accompanied by the words ' my love'.
The bathrobes were sent to Cyrus and Hemsworth by animal rights charity PETA, who described the pair - who were respectively crowned PETA's Sexiest Vegetarian Celebrity of 2015 and 2016 - as 'outspoken animal advocates'.
"Miley Cyrus' and Liam Hemsworth's compassion have inspired countless people to help animals and go vegan," PETA President, Ingrid Newkirk, said in a statement.
"PETA wishes them many more years of promoting kindness to animals together."
