Khloe Kardashian warned her sister Kim that her marriage to basketball star Kris Humphries was doomed before the socialite exchanged vows with the New Jersey Nets player.
Khloe, who is married to former Los Angeles Lakers star Lamar Odom, admits she liked Humphries, but hated the idea of him and her sister as a couple.
In a taped interview with chat show host Ellen DeGeneres, which airs on U.S. TV on Wednesday (11Apr12), Khloe says, "I like Kris as a person. I just did not like them together... I was the only one to tell her. I don't know why no one else told her that.
"She got mad at me. I like being honest. You'll get mad. You'll get over it. You're my sister there is nothing you can do. You're stuck with me."
Khloe also tells DeGeneres she likes the idea of her sister dating family friend Kanye West, but refuses to confirm reports they are in a relationship.
She adds, "We've known Kanye forever. He's been a great family friend. I love Kanye. I don't know what happens with Kim. I love Kanye. I think they're cute together.
"I like Kanye. I think Kim and Kanye have known each other for a long time. I think that they're good friends and they're compatible. I think a friendship is where good relationships stem from."
