Josh Duhamel's adorable son Axl showed his dad what it means to be cool during a Monday Night Football between the Minnesota Vikings and the San Francisco 49ers. Josh took to Instagram to share a sweet snap of his 2-year-old little boy rocking a Vikings hat, writing, "SKOL Vikings!" Of course, this isn't the first time the actor has posted a cute picture of Axl. Over the years, both Josh and Fergie have offered a glimpse into their family life with heart-melting photos of their son.
