There’s not much love between “Keeping Up With the Karadshians” star Kylie Jenner and Madonna’s daughter Lourdes Leon. Even though the reality star extended an invitation to Leon, the singer's daughter thinks Jenner and her famous sisters are “vile,” a source told Radar Online in an exclusive report Monday.

“She couldn’t believe Kylie thought she’d be receptive to a party invite and has completely ignored her -- as far as Lourdes is concerned, she’s not going to lower herself to even responding,” the insider said. “She thinks Kylie and her sisters are vile and has made a big effort to avoid being in the same room as any of them.”

While it’s clear from the source that Leon doesn’t like Jenner, there was no reason given. Even though Madonna’s daughter, 18, might not want to “keep up” with the 17-year-old reality star, there is someone else who is supposedly jealous of Jenner's relationship with rapper Tyga: troubled singer Chris Brown.

It was recently revealed Brown fathered a love child with Nia Guzman while he was in a relationship with Karrueche Tran. After the model found out about it, she dumped the “Loyal” singer. Now, he’s envious of Tyga’s relationship with Jenner after she showed up at a studio where the men worked on together on a video, a source told Hollywood Life.

“Kylie showed up looking red hot to support Tyga. They were hugging and laughing and being themselves. She even brought him a pack of Starburst. Karrueche used to do little things like that for Chris just to spice up his day and show him that she loves him,” the source said. “Chris took a second and just stood there, watching Kylie and Tyga interact between takes.”
