This never even crossed my mind, Robin Thicke is the son of Alan Thicke. Mr Seaver from growing pains, next to each other you can tell the similarities but the thought never even crossed my mind at all. One of the most famous fathers from the 80s, is father to a platinum winning musician. Their characters seem very different, when Robin Thicke comes off as smooth and chill while Alan Thicke comes off as charismatic and upbeat. Now that’s something that I didn’t know.
