The “All of Me” singer will join the Massachusetts Democrat at a pair of stops in South Carolina on Wednesday, her campaign confirmed Friday.
The news was first reported by CNN.
The star-power push from Legend comes ahead of the Feb. 29 primary in the Palmetto State.
The 41-year-old Grammy Award winner had expressed support for Warren’s White House bid in a Vanity Fair interview last year.
“She’s the best candidate running today and she comes at it with joy and with sincerity and with a wealth of knowledge and experience,” Legend told the magazine.
Legend and his wife, model and author Chrissy Teigen, have been vocal critics of President Trump. Speaking at the Democratic retreat last year, Legend referred to Trump as a “joke,” a “con man” and a “clown.”
Warren has found support from a number of high-profile entertainers for her presidential run, including Scarlett Johansson, Amy Schumer, Elizabeth Banks and Sally Field, among others.
