Gwen Stefani and Blake Shelton are really heating things up! On Monday, Gwen took to Twitter and uploaded a short clip of the country singer kissing her on the cheek, adding to their many sweet moments on social media [1]. Gwen captioned the snippet simply, "Merry Christmas gx," along with a Christmas tree and prayer hands emoji. Over the weekend, The Voice coaches took their romance [2] to Nashville, where they celebrated the engagement of RaeLynn, Blake's former teammate on the singing competition show. See Gwen's post below, and then check out when she and Blake channeled The Notebook [3] last week.
