Cry a river for Justin Timberlake, Jessica Biel’s sweet family album

Although the duo have kept their children Silas7 and phineas2, out of the limelight, they even kept Biel’s pregnancy and Phineas’s birth quiet, they have he gave us an occasional peek into his private world. Take, for example, last June when the N’SYNC alum shared a rare snapshot of his son playing the piano.

“My two favorite tunes,” he captioned the image, which showed the boys’ backs facing the camera. “Happy Father’s Day to all dads!”

For her part, the actress commemorated the day with a sweet photo of the foursome hugging each other. “To the world, you are a dad,” she wrote. “But to your family, you’re the world. I don’t know who said that, but whoever it was had that s**t. We love you baby. Thank you for being our everything!”

So yeah, it’s safe to say the couple, who tied the knot in 2012, can’t stop the feeling…of happiness.
