REUTERS\/Mike Blake(Reuters) - Former U.S. first lady Michelle Obama made a surprise appearance during the opening address at the 61st Grammy Awards in Los Angeles on Sunday and was met with a standing ovation from the star-studded crowd. Grammy host Alicia Keys kicked off the show by inviting Obama, 55, along with Lady Gaga, Jada Pinkett Smith and Jennifer Lopez, to share personal anecdotes about how music has changed their lives and empowered them as women. Obama, wearing a shimmering, silver suit, was briefly interrupted as the crowd erupted in cheers and applause at the beginning of her comments. \u201cFrom the Motown records I wore out on the Southside to the \u2018Who Run the World\u2019 songs that fueled me through this last decade, music has always helped me tell my story,\u201d Obama said, referring to the Chicago neighborhood where she grew up. Obama is currently touring to promote her memoir \u201cBecoming,\u201d which was released in the United States and in 28 languages around the world. She and her husband, former U.S. President Barack Obama, signed deals for a book apiece with Penguin Random House a month after Obama left office in January 2017. \u201cWhether we like country or rap or rock, music helps us share ourselves, our dignity and sorrows, our hopes and joys,\u201d Obama said. \u201cIt allows us to hear one another, to invite each other in.\u201d Reporting by Gina Cherelus in New York; Editing by Bill BerkrotOur Standards:The Thomson Reuters Trust Principles.
