It’s no surprise that Jessica Biel‘s household is full of laughs.

In an interview with Today held at her new restaurant Au Fudge during a Mother’s Day event with Tiny Prints and nonprofit organization Baby2Baby, Biel, 34, dished on exactly how her son Silas Randall13 months, is just like daddy Justin Timberlake.

“He is a ham, just like his dad — serious ham. He thinks everything is funny,” she says of Silas. “He thinks sneezing is really funny. He’s in that moment where he thinks bodily functions are really funny.”

Biel’s husband of 3½ years might have made his big break with a (still-hot) music career, but he has flexed his acting muscles quite a bit too — including with multiple hilarious stints on Saturday Night Live and appearances on The Tonight Showhosted by BFF Jimmy Fallon.

About motherhood, Biel also told TODAY that she cherishes the simple moments she shares with Silas the most — kid-friendly yard work and play — and definitely feels the “invisible umbilical cord” now that she’s a mom.

“You’re still connected to that same person, even though you’re not in the same body anymore,” she says. “And that does not go away.”

And his humor isn’t the only way little Silas resembles Timberlake, 35.

“They’re like the same person,” Biel told PEOPLE last month during the Tiffany & Co. 2016 Blue Book dinner. “They like to sit and watch golf together. They just sit there on the couch staring at it. And they don’t communicate anymore. When golf is on, all the communication ends.”
