Sharing an update with nearly 40,000 followers across Instagram and Twitter, Indy wrote:
"Plot twist (I like boys and girls)."
Indy, who has recently released a book of poetry called Sticky Notes, received a raft of praise, encouragement and support online in response to the tweet.
"Proud of you! Hopefully one day we'll live in a world where this won't be considered a plot twist," one tweet read.
"We welcome you, queen," read another comment.
The 19-year-old went on to thank fans and followers, writing, "today was so amazing".
"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."
The young writer is planning a tour to promote her new poetry book, following in the footsteps of her mother Sonja Yelich, an award-winning New Zealand poet.
