On Saturday — triple-threat powerhouse who still fronts the boy band of my heart — Justin Timberlake took to Instagram to post an sweet moment with his son, Silas. Timberlake and wife Jessica Biel welcomed their first child, Silas Randall, on Apr. 11 earlier this year. The belated Christmas Instagram shows Timberlake giving a very bundled-up Silas a kiss on the cheek. Awww! Too precious. Timberlake added the following caption to this too sweet moment: "This life... Truly the GREATEST gift ever. Hoping you are spending time with the ones you cherish and remembering that we are ALL family. Sending love from ours to yours. Merry Christmas, everyone!! --J and J and S"

We all knew he was going to be an amazing dad from the day he posted that amazingly sweet Instagram of Timberlake kissing his wife's very pregnant belly. And then when he teared up during his acceptance speech at the iHeartRadio Music Awards about becoming a new dad... *swoon* Seriously, how do your ovaries just not explode when you hear Timberlake say things like: "Lastly, you can't have innovation without creation. So finally, I want to thank my best friend, my favorite collaborator — my wife, Jessica, who's at home watching. Honey, I can't wait to see our greatest creation yet." Oh stop!

Behold the adorableness of Timberlake's latest proud papa photo below:
