Kim Kardashian didn't know in advance about Kanye West's decision to run for President

Reality TV star Kim Kardashian says she was taken aback by her rapper husband Kanye West's announcement to run for US president in 2020.

"That was news to me. That wasn't a discussion in our household. I believe he is serious and I know that if he puts his mind to something he'll do his best. And he will," Kardashian said on "The Ellen DeGeneres" show.

"You know it's been fascinating just hearing all of the conversations that have gone on since that announcement. I don't know if that was planned and I just didn't know about it or if he came up with that idea right then and there," she added.

The rapper made headlines when he said in an interview with Vanity Fair that he's not joking about running for president.

"I didn't approach that because I thought it would be fun. It wasn't like, 'Oh, let's go rent some jet skis in Hawaii.' No, the exact opposite," he claimed.
