Gwen Stefani sent the sweetest birthday greeting to Blake Shelton

Sometimes it feels like Blake Shelton and Gwen Stefani have been together forever. But really, it’s only been since late last year. Times flies when you’re the most adorable celebrity couple around! Blake and Gwen are not shy with their affection for each other, and they show a lot of love on social media whenever possible. (Their Twitter profile pics are of each other, you guys.)

Blake’s birthday was yesterday, and Gwen celebrated in the cutest way. He turned the big 4-0, and she took things to the next level by posting throwback pics of her love on Instagram and Twitter.

Look at young Blake. SO cute.

Seriously, these captions are making us melt. false
