There is nothing sexier than responsibility (and defined abs)!
Yesterday Gavin Rossdale showed his oldest son Kingson, that being a man means taking care of your family.
The rock star was spotted at Whole Foods yesterday with his now brunet boy. Perhaps the fellas are planing to make a big meal for mommy Gwen Stefani.
Kingston used to have blonde locks like his mom, did he turn brown over night??
Not that it matters, this kid will always be cute!
