Kris Jenner's sister blasts the reality TV matriarch

Los Angeles - Kris Jenner has been blasted by her sister.

The showbiz matriarch has "changed" and got caught up in a showbiz lifestyle, Karen Houghton has claimed, but her younger sibling doesn't think the Keeping Up with the Kardashians star is happy.

Karen told RadarOnline.com: "I can't get to her anymore. But I guess it's the money.

"She's a huge celebrity and now she has changed. I'm not saying good or bad. But I've seen what it can do to Kris... ever since she moved to LA.

"I think my sister needs inner peace. She's not warm and fuzzy. She works so hard and making money, but is it making her happy? I don't know.

"I think she needs to laugh more. She's very serious."

Kris has "isolated" herself:

Karen claims Kris - who split from husband Bruce Jenner last October after 22 years of marriage - has "isolated" herself from the rest of her family and she doesn't like her relatives telling her what they really think.

She added: "She's isolating herself from the family. I tried to reach out to her, but she's very aloof.

"I tell her like it is and she doesn't like it. If something makes me upset, I tell her. She doesn't like it because of who she is. I love her, but I tell her how I feel.

"I get pissed off at her because she doesn't respond to me. If you think your sister would call you back, she doesn't. And it hurts me. I don't care how much money you have or who you are, you're my sister. I'm not afraid of her."
