Jerry Seinfeld's wife Jessica proudly shares a snap of son Julian, 18, on his high school graduation

Jerry Seinfeld’s little boy is all grown up and ready to take on the big world. 

Wife Jessica proudly posted a photo of their son Julian holding his cap and gown before his high school graduation on Thursday morning.

In the snap, shared with her 508,000 Instagram followers, the college-bound teen looked handsome in a crisp white button-down with a black and white striped tie. 

The soon-to-be graduate, who will continue his studies at Duke University in the fall, matched his trousers to his navy academic regalia and wore brown leather loafers.

‘GRADUATION DAY FOR MY BABYYYYY JULIAN,’ the mother-of-three captioned the sweet photo, taken just hours before he received his diploma. 

Julian will be following the footsteps of his older sister Sascha, 20, who began her studies at the same prestigious university in Durham, North Carolina in August 2019.

While it’s unclear where Julian attended high school, his sister graduated from Chapin, a private upscale all-girls high school in Manhattan’s Upper East Side.  

 Major milestone: In the snap, shared with her 508,000 Instagram followers, the college-bound teen looked handsome in a crisp white button-down with a black and white striped tie (the whole family pictured last February) 

Sascha previously interned for The Tonight Show Starring Jimmy Fallon and, more recently, worked as an Assistant/Stage Manager for Duke Performances in 2020. 

Additionally, she has earned credits in 2007’s Bee Movie and PBS News Hour (2020). 

Jerry, 67, and Jessica, 49, also have a younger son, 15-year-old Shepherd Kellen.
