Khloe Kardashian has posted a cryptic tweet about family loyalty after her brother Rob was romantically linked to Blac Chyna.
Just hours after the model shared a picture of herself on Instagram, embracing a tattooed man - whose inkings match Rob's - Khloe took to Twitter to post what could be interpreted as a warning message, which read: "You can do anything. But never go against the family."
The new romantic relationship comes with a great deal of baggage as Rob and Khloe's 18-year-old sister Kylie Jenner is currently dating Blac Chyna's 26-year-old ex-fiance Tyga.
Blac, 27, is also the mother of Tyga's son King Cairo and has been locked in a bitter public feud with Kylie ever since the teenager started dating her ex.
She also used to be best friends with Kylie's sister Kim Kardashian West, 35, but they are no longer close.
Meanwhile, it has been claimed that Kylie and Tyga are "not on the best terms" at the moment.
The 'Keeping Up With The Kardashians' star and the 'Rack City' hitmaker's relationship has been recently rocked by cheating allegations but the pair are trying to work through their problems.
A source told PEOPLE magazine: "They are together but aren't on the best terms. They have a very 'high school' relationship and argue and bicker all the time about stuff for no reason, and that's because Kylie doesn't trust Tyga after all the reports came out about him cheating. It's made her really rough around the edges when it comes to him."
