John Legend has said he is "disappointed" with Kanye West for his meeting with President-elect Donald Trump, which he has described as a "publicity stunt".
The rapper met with Mr Trump at Trump Tower and said that he did so in order to discuss "multicultural issues".
Singer-songwriter Legend, who has collaborated with West in the past and who has connections with West's GOOD Music record label, expressed his opinions about the encounter to French media outlet Clique.
Legend said: "I don't think it's impossible to talk to him about issues, but I won't be used as a publicity stunt. I think Kanye was a publicity stunt.
"I'm pretty disappointed with Kanye that he says he would have voted for Trump. I think Trump has been corrosive, his message has been corrosive to the country."
He said: "I think the things he has promised to do have been very concerning for a lot of people, and for Kanye to support that message is very disappointing."
The All Of Me singer said that he does not think it's "impossible to talk to [Mr Trump] about issues, but I won't be used as a publicity stunt".
He said: "I think Kanye was a publicity stunt."
Legend said that "whatever's in his mind, I disagree with him".
West and Mr Trump spoke about "issues including bullying, supporting teachers, modernising curriculums, and violence in Chicago", the rapper revealed in a tweet on Wednesday.
In what was his first Twitter post for almost two months, West wrote: "I feel it is important to have a direct line of communication with our future president if we truly want change."
West previously announced his own plan to run for president in 2020, but tweeted "#2024" after the meeting with the president-elect.
The 39-year-old posed for photos in the lobby of Trump Tower with Mr Trump after the meeting, and when asked why he was not speaking replied "I just want to take a picture right now".
Mr Trump said the two were "just friends" and that they discussed "life", describing the musician as a "good man".
Last month, the star, who is married to Kim Kardashian West, said he did not vote in the US elections, but if he had done so, he would have backed Mr Trump.
