“In time, and when everyone is able to, there will be more to say.
The memories we shared with him will be treasured forever.
We will miss him terribly.
We love you Liam.
Liam was somebody I looked up to everyday, such a positive, funny, and kind soul.
And for the record, Liam was in my opinion the most vital part of One Direction.
His experience from a young age, his perfect pitch, his stage presence, his gift for writing.
The list goes on.
Thank you for shaping us Liam.
I would have loved to share the stage with you again but it wasnt to be.
I wish I got chance to say goodbye and tell you one more time how much I loved you.
Payno, my boy, one of my best friends, my brother, I love you mate.
Liam was always so kind to me.
He was one of the first major artists I got to work with.
I cannot believe he is gone…. Puth and Payne collaborated on Paynes 2017 single Bedroom Floor.
May he rest in peace.
I really like Charlie.
