It's frequently rumoured that they are planning to get engaged in the near future.
And while there may not be a ring on her finger just yet, there's No Doubt that Gwen Stefani and Blake Shelton's relationship is extremely serious.
The 47-year-old pop star and the 40-year-old country crooner spent Thanksgiving with both of their families on Thursday.
Gwen shared a sweet photo to Instagram which showed her locking lips with Blake, along with the caption: 'Happy thanksgiving we love u sooooooo grateful !!!! Gx'
She followed up with a second snapshot in which she was cuddling up for a selfie with her man and his mother Dorothy.
Gwen later posted Snapchats of the two turkeys that were being served at dinner: one cooked by Blake, and the other cooked by her father Dennis.
The Make Me Love You hit-maker's niece Stella had even drawn pictures of the happy couple to serve as place cards.
