David Beckham has been able to remain a style icon, and with father's day approaching we're checking out how these stylish celebrity dads stay on trend. David's casual style is often reminiscent of his teenage sons but Harper Beckham may be the girl behind her Dad's rocking style. From his Instagram it seems she's always willing to lend him a hand with his outfit. We recently spoke father of two Neyo, and asked him how he stays cool. And for Simon Cowell his latest accessory always keeps him looking great, sadly you can't buy this at the shops as it's his baby, Eric.
