Reese Witherspoon took to Instagram on Friday to wish her eldest son, Deacon Phillippe, a happy birthday. She shared a photo of herself and Deacon, who turned 12 years old, writing, "Happy birthday to my sweet 12 year old boy! You bring joy to everyone you know. I feel so blessed to be your mom." On Saturday, Reese followed up her wish with a shot of his golf-inspired cake with the caption, "The only cake for a golf loving kid. #golfer #12 #birthdaycake."

The last couple of months have been filled with birthdays for Reese, who treated her lookalike daughter [2], Ava Phillippe, to some retail therapy [3] on Thursday. After celebrating her daughter's 16th with a special shout-out [4] on Instagram in September, she honored her little boy Tennessee Toth's big day with two sweet snaps [5], adding to her collection of frame-worthy pictures [6] on social media.
