As Shelton noted, we’ve seen him pal around with her boys plenty over the years, and it’s pretty clear that they enjoy spending time with him, as he does with them, but when you spend so much time with kids, they’re bound to pay attention to what you say and do (and possibly take away unintended lessons from that) and this is one such area where some unexpected responsibility would come in.
Obviously, anyone with a career as strong as Blake Shelton’s already knows a thing or two about responsibility, but he probably didn’t fully consider the brand new obligations he would take on by beginning to date Gwen Stefani.
