Gwen Stefani calls Blake Shelton 'a liar and a cheater'

A few seasons ago, when Kelly Clarkson joined "The Voice," NBC made over the show’s iconic red chairs with snazzy new extras like heated seat cushions and shiny chrome cup-holders. This season, to welcome back coach Gwen Stefani, Gwen’s boyfriend Blake apparently decided to upgrade his own chair… with a red button that plays Gwen’s hit “Don’t Speak” on demand whenever he wants to silence any of his rival coaches. It was going so well until Blake hilariously, accidentally hit his “Don’t Speak” button while getting worked up trying to win over contestant Kiara Brown -- thus effectively silencing himself mid-sentence and giving his secret away. Gwen was so faux-shocked that she called her own significant other a “a liar and a cheater.” Kelly additionally accused Blake of “sitting on a [red, spinning] throne of lies” and John Legend said, “I don't know how Gwen can be in a relationship with someone who has this many problems with telling the truth!” Blake, obviously intent on maintaining his track record as the winningest contestant in "Voice" history, merely shrugged, “I have my tactics I use to get artists that I want on my team. I'll stop at nothing, even if I have to lie to these three” – though he admitted that he’s “got to be better at lying” if he expect to win this season. But it was all in good fun. Kelly was laughing so hard she nearly toppled over, cackling, “That was maybe my favorite part of anything I've seen on 'The Voice!'” Gwen actually busted a move to her own song, and she probably will enjoy any iTunes or Spotify spikes the Tragic Kingdom ballad might get from all this NBC exposure. (Admit it: “Don’t Speak” is totally lodged in your brain now. This was the best use of the song on "The Voice" since Hunter Plake covered it in Season 12.)
