Reality TV star Kim Kardashian said she believes her husband, Kanye West, is being serious about his desire to run for president.

On Wednesday's "The Ellen DeGeneres Show," Kardashian, 34, said West's announcement at the MTV Video Music Awards that he wanted to run for president in 2020 "was news to me. . . . That wasn't a discussion in our household."

Nevertheless, she said: "He's serious. I believe he is serious and I know that, you know, he -- if he puts his mind to something he'll do his best. . . . 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."

Noting, "That's a big thing to not talk to your wife about," the "Keeping Up With the Kardashians" star nonetheless conceded, "I think that would be so much fun to be in the White House."

She added: "I was joking with him. I was like, 'You're going to have to make it to a second term,' because he loves redecorating. So I was like, 'You're going to want to, like, redo the whole White House and we're not going to be able to enjoy it, so we're going to have to just go with the flow.' "

Kardashian, who is expecting her second child in December, also said she and West, 38, haven't chosen a name for their son and that they will "start thinking [about names] at about eight months" into her pregnancy. After fielding DeGeneres' jokes about naming the child "Wild," "Mid" or "East Meets," she admitted: "I do like the name Easton. Easton West. I don't think my husband likes that name, but I do like it."

She stressed: "It's definitely not South. Every time someone says, 'South,' I just want to roll my eyes. It's not a good direction."

Kardashian and West are parents to a 2-year-old daughter, North.
