On Christmas Day, the 34-year-old singer posted the father-son pic on Instagram, complete with a touching message that would force the most dedicated Scrooge to embrace the holiday spirit.
"This life... Truly the GREATEST gift ever," he captioned the photo. "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."
The struggle to fight back tears is so real right now. To date, Justin has shared plenty of sweet moments with his baby boy on social media, including Silas' first Instagram photo and a shot of the duo spending time together on their first Father's Day that was so cute it nearly sent us over the edge.
SIGH. Honestly, there's nothing like a cuddly kid photo to get those happy feels flowing. Keep 'em coming, JT.
