Blake Shelton posted a sweet song on Instagram to wish Gwen Stefani a happy birthday.

He posted the cutest photo on his Instagram account!

Gwen Stefani’s husband-slash- Voice Coach, Blake Shelton, celebrated her birthday on October 3rd.

On October 3, Shelton uploaded a photo of himself and his partner. Although the subject is yet to be identified, it seems that the two are in love.

The pop star was dressed in her signature look. Lorde was seen wearing a navy shirt and darkwash jeans.

“Happy birthday to my beautiful wife @gwenstefani!!! I love you so freakin much!!!!” the enthused country star captioned.

Stefani and Shelton fell in love when Stefani joined as a coach and wrote "You're Mine" for him during one of their meetings.

And they are still together! After seven years, they finally got married in July 2021! Shelton even told the interviewer she was his girlfriend (aww!).

The Voice airs on Mondays and Tuesdays at 8/7c on NBC and you will be able to watch it the day after on Peacock.
