Jerry Seinfeld's wife gave fans a rare glimpse of the actor's lookalike son in a recent post.
Jessica Seinfeld shared a heartfelt happy birthday message to their son Julian in honor of his birthday.
"Happy 20th Birthday to @julianseinfeld! Your work ethic enables you to balance a heavy college course load with a job you love," she wrote on Instagram. "Your sharply tuned BS detector suffers not one fool. The moral high bar you set for those around you keeps us all in line. You chose your friends wisely, and treat them all like family."
"You are such a phenomenal and gorgeous human being. Your goodness is greatness, especially in this world today," she continued. "I love you, my sun."
Jerry added his own message in the comments writing, "We love you so much, Jules. Happy Special Birthday this year!!"
JERRY SEINFELD RECALLS MOMENT CAST KNEW ‘SEINFELD’ WAS OVER: ‘SHOULDN’T PUSH OUR LUCK'
Julian currently attends Duke University along with his sister Sascha Seinfeld.
The comedian has previously admitted his kids do find him funny, just not all the time.
"But if I'm not, which occasionally, of course, humor is a very hit-and-miss business, as we know. And when I'm not, believe me, they will take me out at the knees," Jerry told NPR in a 2020 interview. "They will. They'll look at me and just go, 'That's it? That's all you got?'"
The "Seinfeld" star also claimed he's "very hard" on his family when it comes to humor.
"Kvetching is only of value if you can do it in an amusing way," he says. "My son just came in a minute ago and he says, 'I can't study. The wind is howling.' I said, 'We can't say things like that.' If you're going to complain – my whole act is, of course, constant complaining – but you have to find something amusing in that complaint. Otherwise, keep your mouth shut."
"I'm very hard on my family as far as being entertaining. You know, at my dinner table, you're supposed to be funny."
