None other than Blac Chyna is offering advice to Kylie Jenner amid growing rumors of her pending nuptials to Chyna's rapper ex-boyfriend Tyga.

"Get a prenup," Chyna advised.

The outspoken entertainer and model delivered her terse and unsolicited advice to her rival via an Instagram video she posted over the Labor Day weekend, in which she lip-syncs to Drake's Meek Mill diss track "Back To Back."

In the money shot, a devilish looking Chyna smirks to the line, "Shout out to my boss b*tches wifing n*gg*s. Make sure you hit him with the prenup."

Radar Online reports the diss is the latest in a seemingly never-ending exchange between the two ever since Jenner publicly began dating the rapper.

Chyna has had a field day with recent reports that the Lamborghini the apparently cash-strapped rapper bought his girlfriend for her 18th birthday was actually leased in her name. Rumors that Jenner also recently paid his rent and has asked mom Kris Jenner to take him on as a client have also served as juicy material for Chyna.

All the trash talking recently prompted Tyga to take to social media himself to berate the mother of his child for, among other things, driving an Audi similar to the one he himself once got around in.

Given all the bickering and fighting, Jenner has now launched an anti-bullying campaign, but fans have instantly and endlessly blasted it as "self-serving and disingenuous."

As for their union, recent rumors have indicated the two are even considering eloping. In addition, the pair are also reported to be contemplating moving away from L.A. to get away from all the drama that has overrun their lives. Among leading potential destination spots are said to be New York City and Europe.
