Uh, isn't he their manager?

He's like their boss so

he stan for the gurls but he doesnt try to promote them.. n dont get the budget for music videos like 1D.. bye

I'm not surprised

So nice to see him speaking publicly about their success.

He always has good words for the girls. In his career, he never had a successful girl group which he was involved in a lot (Little Mix won when he was not on The X Factor UK), so I guess that's why he loves the girls so much. They're Simon's girl group.
