Jessica Biel is making the holiday season extra mischievous and fun.

The Illusionist actress, alongside her husband Justin Timberlake, is delighting their children with creative and playful Elf on the Shelf antics. Their two sons, Silas, 9, and Phineas, 4, are enjoying a series of imaginative and cheeky setups that are sure to become treasured holiday memories. This engaging family tradition has become a source of joy and laughter, as they eagerly await the elf’s playful surprises each morning.

Recently, Jessica shared a collection of entertaining photos on her Instagram, revealing their family elf caught in some hilariously questionable situations. From employing one of the boys’ toothbrushes as a “butt brush” to ziplining across the living room with a Spiderman action figure as his partner in crime, this elf is truly embracing the spirit of festive mischief and naughtiness this holiday season.

The 42-year-old actress humorously acknowledged the elf’s antics in her Dec. 24 post with a straightforward, yet cheeky caption: “naughty ass elf.” This playful acknowledgment perfectly captures the light-hearted nature of their family’s holiday fun.

Interestingly, it seems this mischievous elf might be trying to send a warning to Silas and Phineas about their behavior. He left behind a playful note that reads, “You better stay off the naughty list, or I’ll paint your face FOR REAL.” The note included an illustration of the boys adorned with marker mustaches and beards, cleverly demonstrating the elf’s warning with an arrow pointing to their comical photos, “just like this.”
