Police are investigating a break-in and robbery at Blac Chyna's home over the weekend (30Apr-01May16).
Her fiance Rob Kardashian reportedly called the cops after the model realised someone had opened her safe and stolen over $200,000 (£136,290) in cash and jewellery.
Law enforcement officials tell TMZ all signs point to the culprit being someone close to Chyna, as the safe in her Tarzana, California home was not damaged.
The news comes just a day after it was revealed someone is shopping a Blac Chyna and Tyga sex tape around porn sites and media outlets.
The Rack City rapper dated the model, who is the mother of his three-year-old son King Cairo, for three years until 2014. He is now dating Rob Kardashian's half sister Kylie Jenner.
Blac Chyna, real name Angela White, is reportedly trying to suppress the tape, and her lawyer has told TMZ they will take legal action against anyone who releases it.
The release of the sex footage could dredge up the Kardashian-Jenner drama again just days after Kylie and Blac put feud rumours to rest by posting a joint mirror selfie to Snapchat.
Kylie wrote in the caption, "when we've been best friends the whole time..." and in another Snapchat image, Blac wrote, "Hanging out with my lil sis".
Meanwhile, Tyga publicly declared he was happy for Blac and Rob on Twitter days after they announced their engagement, writing: "Everybody deserves 2 be happy. What some1 does for their happiness is not my concern, as long as it's not interfering wit my happiness (sic). It makes me happy to see the mother of my son happy."
