Justin Timberlake's Instagram tribute to wife Jessica Biel's birthday might make your toes curl with happiness. Or it might not—depending on how dead inside you are. Either way, HBD, Bielsy!

The "Mirrors" singer shared an adorable photo of the kissing couple celebrating Biel's 34th birthday on Thursday, and tacked on a meaningful message.

"Happy BAE-DAY, baby!!" Timberlake wrote on Instagram. "I can't put into words what you mean to me... You are the GREATEST Mommy and Wife a man could ever ask for. I love you to the MOON AND BACK!!! --Your Huz"

Now doesn't that just warm your heart like a cuppa apple cinnamon tea?
