Although some people may have thought Blake Shelton and Gwen Stefani’s PDA was a little overbearing when they both coached Season 12 of The Voice, no one can deny the amount of adorableness that exudes from them as a couple.

The No Doubt singer recently celebrated her 48th birthday (October 3), and her country star beau sent her the sweetest birthday wish via Twitter.

“Happy Birthday Gwen Stefani!!! Why don't you go ahead and NEVER break my heart!!!!” he tweeted—and the world let out a resounding “Awwww!”

The couple has been together since 2015 and recently released a festive duet, “You Make It Feel Like Christmas,” that will make your heart melt.
