Yeah ,you are right. I meant Kelly Clarkson and Because Of You is one of my favorite songs. 

Beckham, of course, is David Beckham. You must know him. anyway, thank you so much :)

Ok, well, make sure to use people's full names. They are really important in making clear who you mean. For instance, I assumed you meant R. Kelly and David Beckham when you wrote this because they are the most famous people with those names. However, you actually mean Kelly Clarkson and Clark Beckham, right?

I had never heard of Clark Beckham before today. I'm sorry I can't answer your question :(

Hi, you know, It's a song from Kelly.Recently I saw a MV about Beckham,and the background music is Because Of You, so I  thought it was created for him

This isn't real clear to me. Can you explain a bit more?
