Aging Jamie Lynn Spears

Why does Jamie Lynn Spears' hair look gray in this cover photo at OK! magazine? Are they trying to make her look older than the "teenager who got knocked up and had a kid" teen that she is?

The baby's name is Maddie Briann. Cute kid considering most newborns look like little old people. I can say that because I've had four of those "little old people" kids.
