The star debuted her new identity on social media on Sunday, three years after revealing to Oprah Winfrey that, "my soul is male."
"From the bottom of my heart, thank you for the love and respect," she wrote on Instagram. "I love you back and I'm sending peace to everyone."
Previous posts from the singer online have now been deleted, starting fresh as Jake.
On Monday, Jake tweeted about the change, writing, “My first tweet as Jake. Overwhelmed. Saw all your love comments and I’m so happy. Finally. I love you, everyone and see you soon.”
