His Parents Are Susan Sarandon and Tim Robbins. That’s the Joke.

In a series of videos, Jack Robbins has been lampooning nepo baby culture — and embracing it — with help from his parents and Steven Spielberg’s daughter.

For Jack Henry Robbins, the day begins with stretching and meditation, followed by two to three seconds of tooth brushing. After visiting his favorite neighborhood coffee shop, a Nespresso boutique on the Upper East Side, he returns home to begin work.

“Every day, I like to wake up and I either sell a show to HBO or Netflix based on my mood,” Mr. Robbins tells the camera. “Today, I’m pitching a TV show I thought of yesterday that is basically ‘Star Wars’ set in a sewer system — I sold it!”

Triumphantly closing his laptop, Mr. Robbins adds, “I’m off to visit my famous mom.”

That, anyway, is how Mr. Robbins, the son of the actors Tim Robbins and Susan Sarandon, portrayed himself in “Day in the Life of a Nepo Baby,” a video he posted to Instagram last November that has been viewed more than three million times.

Since then, Mr. Robbins, 35, has released a series of over-the-top clips on Instagram and TikTok purporting to pull back the curtain on what it’s like to be the child of celebrities.

The phrase nepotism baby — nepo baby for short — has been used to attack people whose professional accomplishments are perceived by some to stem from family connections rather than talent alone. In his videos, Mr. Robbins appears to lampoon the concept of being the pampered, freeloading son of Hollywood royalty, but also embraces it.
