Rob Kardashian and Blac Chyna‘s daughter Dream Kardashian has reportedly been clashing at her elementary school with a fellow nepo 𝑏𝑎𝑏𝑦.

The eight-year-old reality star allegedly argued with the daughter of The Challenge star Cory Wharton over which of them is ‘more famous,’ he revealed recently on MTV’s Official Challenge Podcast.

According to Cory, 33, he had to ‘humble’ his daughter Ryder, seven, when he tried to defuse the situation.

Cory, who shares Ryder with his ex, Teen Mom star Cheyenne Floyd, explained that ‘All [Ryder has] known is television.’

‘Some more tea,’ he continued. ‘Ryder’s in class with Dream Kardashian. And Dream and Ryder were getting into an argument about who is more famous.’

He stopped to emphasize that both girls were only in ‘second grade.’

Cory wisely didn’t try to determine which reality-star 𝘤𝘩𝘪𝘭𝘥 was more famous, and instead urged his daughter to try to avoid the conflict in the first place.

‘I’m like, “Ryder, don’t you ever argue with a Kardashian,”‘ he joked. ‘We’re gonna step to the side on this argument next time.’

Cory is best known for appearing on MTV’s Real World and multiple seasons of its spinoff series The Challenge, as well as Teen Mom OG, on which he appeared with Ryder’s mother Cheyenne Floyd.

He also shares two younger daughters — Mila Mae, four, and Maya Grace, two — with his girlfriend Taylor Selfridge, 30.

Although Dream’s father Rob has largely eschewed the spotlight in recent years after his appearances on his family’s first reality series, Keeping Up With The Kardashians, dried up, she has remained a strong presence on social media thanks to her own Instagram account.

Dream also regularly spends time with her famous aunts — Kim, Kourtney and Khloé Kardashian and Kendall and Kyle Jenner — and their internet-famous 𝘤𝘩𝘪𝘭𝘥ren.

Rob’s relationship with Dream’s mother Blac Chyna (real name: Angela White) began in January 2016.

The couple announced they were engaged in April of that year, and a month later they revealed that they were expecting a 𝘤𝘩𝘪𝘭𝘥 together.

Cory claimed seven-year-old Ryder (R) had been arguing with Dream at school about who was more famous. ‘I’m like, “Ryder, don’t you ever argue with a Kardashian,”‘ he joked

Dream’s mom Blac Chyna (L) began dating Rob in January 2016 and got engaged in April. Dream was 𝐛𝐨𝐫𝐧 in November 2016, but the two split a month later and were on–off for much of 2017 before splitting for good; seen in May in LA

Dream arrived in November 2016, but the couple had split by the following month.

Rob and Chyna had a tumultuous 2017 with multiple apparent reunions and altercations, including one incident in which she allegedly held a loaded gun near him.

Later in 2017, Rob posted nude photos of his ex as part of a social media post in which he also accused her of infidelities and drug use.

Chyna later sued Rob’s mother Kris Jenner and sisters Kourtney, Kim and Khloé (though Kim was eventually dropped from the lawsuit) for allegedly harming her reputation and leading to the cancellation of her reality series Rob & Chyna.

A jury eventually ruled against Blac Chyna in 2022, though she vowed to appeal the decision.
