You’ll Cry a River Over Jessica Biel’s Elf on the Shelf Chaos for Her Sons

Jessica Biel is bringin’ naughty back.

The Illusionist actress and husband Justin Timberlake have been having a jolly good time setting up mischievous Elf on the Shelf displays for their sons Silas, 9 and Phineas, 4.

Indeed, the mother of two shared a series of photos to her Instagram, catching their family elf in the middle of some questionable situations. From using one of the boys’ toothbrushes as a “butt brush” to ziplining through the house with a Spiderman action figure as his accomplice, there were no limits to this elf’s naughtiness this season.

The 42-year-old said so herself, writing a simple, “naughty ass elf,” in the caption of her Dec. 24 post.

But perhaps this deviant elf is trying to warn Silas and Phineas not to model his behavior. After all, he left the kids a note—or a warning, rather.

“You better stay off the naughty list, or I’ll paint your face FOR REAL,” the note read, with an arrow pointing to pictures of the two with marker mustaches and beards drawn on them, “just like this.”
