And I feel empty, Cowell wrote on Instagram.

And I want you to know how much love and respect I have for you.

Every tear I have shed is a memory of you.

I went outside today, and I thought about so many times we had together.

What is Liam like?

And how much you loved music.

And how much love you genuinely had for the fans.

I had to tell you when you were 14 that this wasnt your time.

And we both made a promise that we would meet again, Cowell said.

A lot of people would have given up.

You came back and within months the whole world know Liam.

And you never forgot the fans.

I watched you spending so much time with people who had wanted to meet you.

Cowell recalled that Payne met up with him last year, Not for a meeting.

Just to sit and talk, adding, We reminisced about all of the fun times we had together.

And how proud you were to be a Dad.

And he will be so proud of everything you achieved.

And how you achieved it.

I always thought the 5 of you in the band as brothers.

And regarding their messages today I believe you were, Cowell continued.

And now Liam, I can see the effect you had on so many people.

Because you left us too soon.

Rest in peace my friend.
