The singer posted on his Instagram page on Saturday, two days after the holiday, a video the actress took of him doing push-ups outside while the 2 and 1/2-year-old boy rides on his back. It marked a rare glimpse at the notoriously private couple's son, whose face is not shown in the clip.
"Shaking off those leftovers like... Hope everyone had a great Thanksgiving! @jessicabiel," Timberlake wrote.
The family ate well on Thanksgiving, especially when it came time for dessert! Biel posted a photo of a cake and three pies, including a pumpkin meringue one that Timberlake later brûléed with a chef's torch.
"Thanksgiving is lit thanks to that #dadlife. @justintimberlake," she wrote.
