You'll probably recognise Teddy Geiger as one of the early '00s heart-throbs that you had posters of on your bedroom wall and stuck to your school books.
His song 'For You I Will (Confidence)' dominated the charts way back when and since then, he's decided to work behind the scenes and write music for big artists like One Direction and Shaun Mendes.
He's a real legend.
Yesterday, Teddy took to Instagram to make a very big announcement.
A fan has asked him why he had started dressing differently over the last few months and that's when the songwriter decided to announce that he is transitioning.
In a very short post, Teddy said that he had already spoken to his close family and friends about his decision and that it was about time he let his fans know as well.
"Okay... because you asked so nicely... I am transitioning.
"I started talking about it with a couple of my close friends and family about a month ago and it's given me the courage to start the process.
"I feel like the next step is to tell y'all. So here goes.
"Love it or hate it this is who I have been for a looooong time.
"I love you guys."
We wish Teddy all the best with his new journey!
