The future of 'Rob & Chyna' is in doubt.
Rob Kardashian and Blac Chyna
Executives at E!, which makes the reality TV show based on the lives of Rob Kardashian and his pregnant fiancée Blac Chyna, have not yet ordered a second season because of tension between the pair.
TMZ reports that the couple have been refusing to shoot scenes together and Rob, 29, is returning to his reclusive ways
This has led show bosses to worry that if they signed up for a second series, Rob would not commit to a full season.
However, TV executives have been hugely impressed with Chyna and would consider giving her a solo show if Rob doesn't commit.
Meanwhile, the couple - who got engaged in April following four months of dating - are set to welcome their first child into the world in November, but the run-up to the birth hasn't been the easiest as it's believed they've barely been talking to each other.
The pair have locked horns a number of times on 'Rob & Chyna' and it's thought the once-reclusive star is struggling to keep up with the filming schedule.
Although 'Rob & Chyna' has put a lot of pressure on their relationship, friends are convinced that they truly love each other and their romance will go the distance.
An insider previously said: "Filming the show has been a lot of stress on their relationship. Add to that Chyna's pregnancy and the fact that Rob and his moods go so up and down. But Rob really loves Chyna."
Chyna, 28, also has three-year-old son King Cairo with her ex-boyfriend Tyga, who is now dating Rob's half-sister Kylie, 19.
