Lorde's teenage sister Indy Yelich-O'Connor has come out as bisexual on social media.
The New York-based teenager posted on Twitter and Instagram today saying: "Plot twist (I like boys and girls)."
Social media users sent Yelich numerous messages of encouragement and support.
"Proud of you! Hopefully one day we'll live in a world where this won't be considered a plot twist," a Twitter user said.
"And after the plot twist there's a happy ending because we love and support you all the way, no matter what and I happen to be gay so today's going to be a good day!! Indy you're amazing, never doubt love," another user said.
Yelich, who recently released a book of poetry called Sticky Notes, has thanked followers for the support.
"I had so many messages of support and the sun was shining, and I just love New York. So grateful for my life and all the people in it," she wrote.
‘This has been a really fast rollercoaster ride of a journey.'
