Rob Kardashian used Twitter to reach out to his siblings. In a report from Entertainment Tonight, Kim Kardashian talked about her love-hate relationship with her younger brother.

"He sends me funny voice notes all day long," Kim Kardashian said. "He always has, it's his thing."

"So he was sending me funny ones last night of him singing, which had nothing to do with the tweet helping me with my nausea. I think he was just trying to make me feel better singing," said the pregnant 34-year-old reality star.

The wife of rap superstar Kanye West also shared how her 28-year-old younger brother is doing much better after rumored bouts with depression.

"He has been [in good spirits], and that always makes me happy," Kim Kardashian said.

Entertainment Tonight detailed how Rob Kardashian used Twitter to make peace with his pregnant sister.

"I thought this nausea thing was supposed to be gone by now!" Kim Kardashian tweeted earlier this June.

Millions of followers were surprised when Rob Kardashian responded to the Twitter post of his famous sibling. The two have been open about their love-hate relationship, with most of their conflicts documented in their family's hit reality series "Keeping Up with the Kardashians."

"I sent [you] that voice note. It should help," Rob Kardashian said via Twitter, followed by more light-hearted exchanges between him and Kim Kardashian.

Another proof of Rob Kardashian's reconciliation with his sisters is an Instagram post by their "momager" Kris Jenner. The mother-of-six recently shared a screenshot of her children's message thread, wherein Rob Kardashian said he loves his sisters and fondly called them his "babies."

Prior to Rob Kardashian making nice with his siblings via Twitter, a report from Radar Online claimed that he is planning to make a career comeback via "Dancing with the Stars."

"Rob's been given an open invitation to visit the show," an insider said.

"Producers even dangled the prospect of serious hang time with Rumer Willis and Charlotte McKinney. Rob hasn't ruled it out."

"The happiest anyone ever saw this kid was when he was dancing every day," the insider added, referring to Rob Kardashian's "Dancing with the Stars" stint years ago.
