Alan Thicke, the Canadian actor best known for his leading role in the 1980s sitcom 'Growing Pains' as well as being the father of singer Robin Thicke, has died, a source close to the family said on Tuesday. He was 69. The Los Angeles Times, quoting Robin Thicke's publicist, said the actor died of a heart attack. More recently Thicke was set to appear in 'Fuller House,' a remake of the popular 1990s family sitcom. 'Season 2 Fuller House looking good. I even like the ones I'm not in!' Thicke said in a tweet earlier on Tuesday.
