Country stars Miranda Lambert and Maren Morris wowed viewers with their Grammy performances. Lambert rocked a low-cut sequined minidress while singing her hit "Bluebird." She later introduced Morris, who wore a red satin gown and sang "The Bones" with John Mayer. Morris spoke highly of Mayer, describing him as respectful and thoughtful. Both singers made outfit changes for their performances. Morris wore a silk Dolce & Gabbana gown on the red carpet, and her dress had an open back with jeweled straps highlighting her back tattoo.
