Blake Shelton (47) is making a strong case for the fact that he's Gwen Stefani's (53) number-one fan.
The Oklahoma native shared a post to his social media last weekend, where he promoted his wife's new track, titled “True Babe.”
In his caption, Shelton wrote, “My wife put out a new song today.. you know... THE GWEN STEFANI!!!!!!! Go listen people!!!! It's a hit!!!!! I'm so proud of you @gwenstefani!!!”
