No wonder we always saw A.J. McLean rockin' all kinds of hats!!
A few days ago, the Backstreets Boys star took to his Instagram to show us his journey through his hair transplant, and we have to admit, we knew A.J. was balding, but we didn't know that his situation had gotten to this point.
However, once we saw the pics of his balding head and then the photo of the brand new him, we were completely blown away.
