"Happy 51st birthday to the man, the myth, the legend, Brian Austin Green! It's hard to believe that such a handsome and talented guy like you has been gracing this earth for 51 whole years. But hey, age is just a number, right? Here's to another year of being the ultimate heartthrob and proving that 51 never looked so good. May your day be filled with love, laughter, and lots of cake. Cheers to you, Brian, on your 51st trip around the sun! #AgeIsJustANumber #HappyBirthday #BrianAustinGreen"
