All celebs employ their mates and friends.
The brothers have been pushing themselves more in the media though, to be fair. They even do sets at his concerts now.
Well yes.....it is their bro's business & he employs them.
Just as making cash is KP's business & she employs her bro as manager & was trying to shove her sister Sophie front & centre for a time in scanty bikini shots etc. No difference.
So neither trumps the other on employing family.
