With the blind auditions and the battles behind it, Season 9 of “The Voice” moved on to the knockout rounds Monday. And speaking of knockouts, Rihanna was on hand (wearing a fetching denim bustier-and-slacks combo) to pitch in as a “key advisor” to all the coaches.
The R&B megastar had no trouble connecting with the contestants and giving them what appeared to be truly useful guidance. But she was clearly more comfortable with some coaches than others: Adam Levine, Gwen Stefani and Pharrell Williams, sure. Blake Shelton? Not so much.
