And as with everything Woods related, the rest of the golf world noticed and several stars from the past and present, including Tiger's niece, took to social media to wish a very happy birthday to the man who inspired an entire generation to take up the game.
Happy Birthday @TigerWoods & all my very best. I really look forward to seeing you win many more in your 40's. Cheers— Gary Player (@garyplayer) December 30, 2015
Happy 40th to the one and only @TigerWoods! The game may be in a great spot, but can only get better with him back in form— Justin Thomas (@JustinThomas34) December 30, 2015
