Rob Kardashian may be having second thoughts about broadcasting his relationship with Blac Chyna on a new reality TV series.

Nearly two months after it was announced that the youngest Kardashian sibling and his bride-to-be had signed on to appear in an E! show titled, “Rob & Chyna,” TMZ reports that the series may be in danger. Rob, 29, is said to have skipped several filming sessions, leaving his fiancée to fend for herself. The Arthur George sock designer reportedly failed to show up to film a celebration of his grandmother’s birthday in San Diego, California. The publication claims that he is worried “Rob & Chyna” will tear him and Blac Chyna apart, as “Keeping Up With the Kardashians” has his family. Sources close to production claim Rob’s feelings on filming “Rob & Chyna” change week by week, which has left the show’s creators worried about collecting enough usable footage.

The show isn’t the only thing Rob’s unsure of lately. In the last few weeks rumors have been swirling about the status of he and Blac Chyna’s relationship. Early last week reports surfaced claiming the pair had called it quits just days after Us Weekly reported that they had got back together following an explosive fight. On July 26 the publication reported that Blac Chyna, 28, was wearing her engagement ring on Snapchat amid reports that they’d called off their wedding.

Rumors that the pair had called it quits sparked up after Rob wiped his Instagram of any and all photos of Blac Chyna. He also unfollowed her on the social media site, further creating doubt in the mind of fans. The alleged split came not long after the couple shared a first look behind the scenes of their impending reality show.

Neither Rob, Blac Chyna nor E! has commented on the fate of “Rob & Chyna.” A release date has yet to be announced.
