While the pregnant model was seen temporarily kicking her fiancé out of their shared home on Sunday's (02.10.16) episode of their reality TV show, 'Rob & Chyna', it has now reportedly become a permanent arrangement.

A source told Us Weekly: "They think it's a healthier way to live."

And it has been claimed that things have turned so bad between the pair, who got engaged earlier this year after a whirlwind romance, that they are now "faking" their relationship for the reality TV cameras and the $2 million payday it brings.

An insider told InTouch magazine: "Rob wanted to make more money even if it meant pretending to be in a loving relationship.

"They are scrambling to hide the truth.

"Chyna wants to make millions from endorsement deals. She's desperate to be as famous as the Kardashians."

Meanwhile, it was recently claimed that the future of the couple's reality TV show is in doubt because of tension between them.

They have reportedly been refusing to shoot scenes together and Rob, 29, is returning to his reclusive ways, leading show bosses at E! to worry that if they signed up for a second series, he would not commit to a full season.

However, TV executives have been hugely impressed with Chyna, 28, and would consider giving her a solo show if Rob doesn't commit.

The pair have locked horns a number of times on 'Rob & Chyna' and it's thought Rob is struggling to keep up with the filming schedule.

Pregnant Chyna also has three-year-old son King Cairo with her ex-boyfriend Tyga, 26, who is now dating Rob's half-sister Kylie Jenner, 19.
