All throughout the story we know that Naruto grew up alone and that his mother died after his birth. But, seeing as he seems to have so many similar qualities to the 4th (blonde hair, stubborn, moves)... does anyone think that the 4th was his dad?

Either that or his dad died in the battle with Kyubba or he's just... one of those runaway fathers... not sure, but I think that the 4th may be his dad...

What do you all think?
