Halsey, Rapsody, Kelly Clarkson and others will either participate with the flowers or have signed on in support of the demonstration.
Members of the music industry will wear white roses to show solidarity for the #TimesUp movement at the 2018 Grammy Awards ceremony on Sunday.
The planned demonstration was put together by Roc Nation senior VP Meg Harkins and Karen Rait, rhythmic promotion at Interscope/Geffen/A&M Records, after realizing that "Music's Biggest Night" was coming without any plan in place to show support for the movement against sexual harassment.
On Monday they assembled a group of a dozen other women in music, calling themselves Voices in Entertainment, and over dinner at a Mexican restaurant in New York City decided to put a plan in place. They chose the white rose because it is a practical and traditional accessory with a symbolic color: The suffragettes wore white during their protests and, more recently, Hillary Clinton wore white at Donald Trump's presidential inauguration, says Harkins.
