Getting older is a state of mind and no one is proving that more than rock legend Steven Tyler. The Aerosmith frontman has always been known for his hippie, colorful, style and that is something that will never change, even if he is a grandpa. Tyler was spotted this week out with daughter Liv sporting striped flare pants and feathers in his hair; and while he had on a more comfortable shoe, Steven Tyler can still claim the title of the coolest dressed dad/grandpa in Hollywood.
