Prior to this post, Shelton broke his silence on social media by tweeting about a particularly tough workout. "Just got off the treadmill. This calls for a drink. Bitch..." he tweeted on Tuesday.

Shortly after posting that message, Shelton removed Lambert's Marie Claire magazine cover as his Twitter cover photo, replacing it with a pic of himself performing.
