Kris Jenner is reportedly pissed off at son-in-law Kanye West for confirming her daughter Kylie's romance with Tyga in his recent radio interview.

"Kris is beyond furious with Kanye for saying Tyga and Kylie are in love," a source revealed to HollywoodLife.com. "She adores Kanye, but this is the one thing that drives her crazy about him -- he can't keep his mouth closed."

The mom-manager has apparently been keeping the 17-year-old's true relationship with the 25-year-old rapper a secret, intentionally.

"Kris knows about Kylie and Tyga's relationship but has purposely kept a lid on it for months because she was scared of the public's reaction -- not to mention the authorities," the source continued. "She was protecting both Kylie and Tyga. Everyone was on board keeping the company line that Tyga and Kylie were just friends. Now Kanye has messed it all up."

While sitting down with Power 105.1's "The Breakfast Club" on Feb. 20, West pretty much revealed that his sister-in-law and T-Raww are dating. However, his original comment was removed from the interview.

"I think they are in love. You can't tell nobody, you know, you can't speak to nobody," he says in the unedited audio portion of his pre-recorded interview, which was leaked online (via TMZ).

The source added that Kris Jenner is the one who ordered the radio station to remove Kanye West's statement:

"Kris had the comment removed from the show because she wantd to protect Tyga. She really likes him and is totally on board with him and Kylie's relationship," the source said.

Meanwhile, West reportedly had a valid reason to say what was not aired on the radio -- it was quite obvious for him to tell that Kylie Jenner was in "in love" with Tyga, according to HollywoodLife.com.

"Kanye can't control what comes out of his mouth, ever. He calls it like he sees it and what he sees from his own two eyes is how much in love Kylie and Tyga are," an insider claimed. "It's obvious to him. She's always talking about him to her sisters. She's always with him and calls his crib her crib. The writing is on the wall for Kanye."
