Kyle Richards' Sibling Feud - 'RHOBH' Star's Sisters Kim & Kathy No Shows at Birthday Dinner

It might have looked like the feud between the Richards' sister was coming to an end, but just when fans believed that Real Housewives of Beverly Hills star, Kyle Richards, and her sisters Kathy Hilton and Kim Richards, had finally moved forward, it seems that a road block stopped them from fixing their relationship. While birthdays are supposed to be the time of year when you get together with your family over cake and ice cream, it seems that Kyle was left to celebrate without her sisters this year.

According to Radar Online, neither Kathy nor Kim attended the celebration, which was held at Craig's in West Hollywood earlier this week. Yet, it seems that one of the absences wasn't a no-show, but rather a snub from Kyle, as she didn't extend an invitation to her sister Kathy. We previously reported the two hadn't made up despite an Instagram post showing otherwise.

"Kim was invited to the dinner but Kathy wasn't," a source explained to the news site. "Things continue to be very tense. Kathy didn't even call Kyle to wish her a happy birthday!"

Yet, while Kim was unable to make it to the event, she did take to her Instagram account to post a cute throwback picture of the siblings together.

Kim also posted the most adorable caption, putting all the feud rumors between her and Kyle to rest, saying, "I've loved you from the day they brought you home Happy Birthday little sister!! I hope this year is best year EVER for YOU!! I love you."

"Kyle knew that even if she invited Kathy, she wouldn't go," the source continued, adding, "there continues to be bad blood because Kyle discussed Nicky's wedding on Real Housewives of Beverly Hills."

However, despite her family not being at the dinner, Richards didn't let it bother her, as she was surrounded by her immediate family and friends, including Kris Jenner and Faye Resnick.

"Kyle felt incredibly blessed to have these long time friends, whom she considers family to be at her side on her birthday," the insider explained, according to StarPulse. "Faye and Kris have always been there for Kyle, especially during times Kim and Kathy weren't."
