Khloe Kardashian warned Kim not to marry Kris Humphries

Khloe Kardashian has confessed she warned her sister Kim Kardashian not to marry "loser" and "dog" Kris Humphries before their wedding.

The Keeping Up with the Kardashians star wed the professional basketball player in 2011 following a seven-month romance. After a televised lavish wedding, their marriage was even shorter, and they divorced after 72 days.

And during an appearance on Snoop Dogg's web series GGN on Tuesday (05Apr16), Khloe revealed she knew their relationship was doomed from the start, and even attempted to convince her older sister that tying the knot was not a good idea.

"There's a ton of times that like, you know, I've told my sister the truth," Khloe revealed. "Like when she wanted to marry Kris Humphries, I was like, 'He's a f**king loser. Why are you marrying this f**king dog?' But she didn't have to hear me, and that's OK. But the fact is I said what I had to say. And I'm not just gonna dumb myself down and act like this guy's not a f**king joke, when, for what?"

Now that Kim's happily married to Kanye West and shares two children with the star, Khloe adds that Kim has since admitted her sisterly advice was right all along.

"So I said the truth, and you know, in hindsight, she was like, 'You were right,'" Khloe said. "And I think that takes a bigger person to come back later and say, 'You know what, sister, you were right.'"

It seems Khloe doesn't approve of another one of her sibling's paramours - she reportedly feels betrayed her brother Rob Kardashian decision to propose to girlfriend Blac Chyna after just four months of dating.

Rob and Blac, Kim's former friend, announced the engagement news on social media on Tuesday (05Apr16), but neither Khloe, Kim or the rest of their family members have publicly made a statement on Rob's new relationship status.

A source tells People magazine Khloe is not happy about the engagement, saying, "Ever since Khloe found out that Rob is dating Blac Chyna, she felt betrayed. This feeling has never changed. After finding out about the engagement, she is furious at the lack of respect.

"She can't believe Rob didn't tell the family in advance. She thinks Rob is causing drama on purpose and wants them (his family) to be arguing."

To make matters more complicated, Blac shares a three-year-old son called King Cairo with her ex-fiance Tyga, who is currently dating Rob's youngest half-sister Kylie Jenner.
