Anyone who's watched their reality show knows that Rob Kardashian and Blac Chyna have quite a fiery relationship.

But things have gotten pretty serious according to TMZ, and now the police are involved.

Rob Kardashian allegedly threatened a male model called Pilot Jones after a series of photos began doing the rounds. In said photos Blac Chyna is kissing Pilot and the two look very cosy. It's unknown when the photos were taken.

LAPD's Threat Management Unit are apparently investigating the allegations after Rob allegedly sent messages that include: 'Leave my wife alone. I'm not playing with you.'

Let's hope it all gets sorted as Blac Chyna is due to give birth to their first child any day now. Their daughter is due on November 16th. A lot has happened in the space of a year for this whirlwind romance, and Chyna could probably do without any extra stress while she's heavily pregnant.

This alongside Kim Kardashian's robbery, which werecently learnt more about, means its not been the greatest time to be a Kardashian but hopefully they'll all pull through together.
