Looks like Reese Witherspoon has raised quite the stylish gentleman.

The actress' son Deacon Phillippe turned 12 yesterday and of course Mom had to go for the embarrassing birthday-suit shot—literally, we mean.

Looking as though they were on their way to a more formal celebration, a dressed-up Reese posed for a pic with her no-longer-baby boy, Deacon wearing a smart navy blazer with on-point red trousers and a most aw-worthy striped bow tie.

The smiling lad, who looks so much like his famous mom (and his adorable dad and gorgeous sister, go figure), had already taken a bite out of the tempting-looking chocolate cupcake he was holding, so no wonder he looked so happy.

"Happy birthday to my sweet 12 year old boy!" Witherspoon captioned the pic, punctuating the sentiment with a cake and other celebratory emojis. "You bring joy to everyone you know. I feel so blessed to be your mom ❤️."

All the feelings.

Deacon's big sister Ava, who just celebrated her sweet 16 back in September, also wished her brother a happy birthday via Instagram, posting the cutest throwback of the both of them riding a roller coast at Six Flags' Magic Mountain.

Reese is parent to Ava and Deacon with ex-husband Ryan Phillippe, who enjoyed a celebratory dinner with his kids for his own big 4-1 last month, and the Oscar winner has a 3-year-old son, Tennessee, with second hubby Jim Toth.

We hope the whole family had a great time celebrating!
