A report claims that Kim Kardashian is "fuming" over Kanye West's crush on her older sister, Kourtney Kardashian. The rumor suggests Kim is going "[c]razy over her hubby's obsession with her smoking-hot big sister," and that she is "not happy about" the situation.

After West released a new song with lyrics that include about "smashing" his sisters-in-law, New Weekly Magazine in Australia claims there is only one particular sister that caught Kanye's eyes, and that's Kourtney. The alleged source has been making the bold claim that Kim and Kanye's marriage is on "shaky ground."

West reportedly "can barely take his eyes off of Kourt," and that he's been "texting [the] newly-single Kourt non-stop lately" now that she's split from Younes Bendjima. The alleged tipster of the magazine also claims that Kim is "slightly worried" about this. What's more is that "rumors are swirling that Kourt might replace Kim as Yeezy's muse, as she was spied at the designer's LA office in June."

But, according to Gossip Cop, Kourtney and Kendall Jenner were both spotted on West's office on June 11. After that, Khloe was also seen on June 18 leaving the rapper's office. On that same day, Kim was also at her husband's office as well. Hence, it is not unusual that any of them being at West's office.

Aside from the reference lyrics of West's new song, the tabloid does not have further evidence to confirm he is crushing and pursuing Kourtney in any way. This rumor only started because of the rap line, and because Kourtney is currently the only one who is single among the Kardashian-Jenner sisters. In previous weeks, West also made clear he is committed to his wife.

Just earlier of this month, he posted a photo of his wife on Twitter with fire emojis as the caption.

On Saturday morning (Aug. 25), Kim also received a surprise gift from her husband in the form of a brand new, neon green Mercedes-Benz G-Class - which she had wanted since their Miami vacation.

Meanwhile, Kourtney Kardashian does have an admirer in Jeezy. The rapper told TMZ that he thinks Kourtney is the hottest among the Kardashian sister, and that he would love for her to call him up so they could get together now that she's single.

When Jeezy was asked about Kourtney's baby daddy and former boyfriend - Scott Disick - he said: "I ain't worried about no Scott. He better be worried about me though," signing off the playful video by saying, "Kourtney, call me!"
