“Keeping Up With the Kardashians” star Rob Kardashian's ex-fiancée, Blac Chyna, made headlines Monday after her alleged sex tape leaked online. Chyna, who became a household name for her relationship with Rob and the feud with the Kardashian clan, has an estimated net worth of $4 million.

Chyna, born Angela Renée White, began trending on social media after the video of the reality TV star engaging in oral sex with an unidentified man was posted by an anonymous Twitter user. Chyna’s attorney Walter Mosley told TMZ the tape’s release is a “criminal matter” and that authorities "will conduct an investigation and determine who is responsible."

Hours after the sex tape leaked, Chyna's lawyer Lisa Bloom spoke out in her defense on Twitter.

“Revenge porn — posting explicit images without the consent of everyone in those images — is a crime, a civil wrong, and a form of domestic abuse,” Bloom tweeted. “It’s also a way to try to slut shame women for being sexual. Girls have killed themselves over revenge porn. It’s not a joke,” Bloom wrote.

“Whether a woman knows she’s being recorded is not the issue,” Bloom said, responding to a user who claimed it seemed both participants in the video knew they were being recorded. “Whether she consented to posting is. Our bodies, our choice, each and every time.”

Mosley also spoke out Monday afternoon, writing on Instagram, “We have to change this culture of abuse and assault against women. Today’s post saddens me deeply as it is an attack not only against my client but my friend. Why do we think it’s acceptable to sell, or publish, or seek revenge, or blackmail women in this way and without their consent? It’s not.”

He continued, “Men … we have to do better. I’m tired of telling my clients to not make videos because the men will put them out later. It’s like I’m telling them not to wear short skirts because you’re going to entice a man to rape you. #smh And like most rapes, these betrayals often come from those most close to us. So today I’m saying, men we need to do better. We need to tell each other to do better. We need to stop sharing these videos with each other in the club, at the barbershop or (and especially) online. It is a morally corrupt action, which is (at least in California) criminal. Maybe it is time to set an example.”

Responding to Us Weekly about the alleged sex tape leak, Mosley said: “Unfortunately, another case of abuse against women. It’s a criminal matter for the police to investigate at this point. I’m following it closely and will make decisions when the time is appropriate.”

In 2011, Chyna dated rapper Tyga and had a child with him named King Cairo. In 2015, she briefly dated professional boxer J’Leon Love before getting involved with rapper Future. Chyna even appeared in Future’s “Rich $ex” music video during their brief romance. In 2016, Chyna and Rob began dating, but their relationship ended in February 2017, just two months after Chyna gave birth to their daughter, Dream.

Last year, Chyna sued Rob for revenge porn after he posted numerous nude photos of her on social media in July. During his rant at the time, Rob said he bought Chyna a purple Lamborghini, which was valued at $200,000. Rob also claimed he spent $100,000 on her post-baby body and gifted her $250,000 in jewelry.

“Today Chyna sent me a video after I just bought her 250K of jewelry and she sends me this video... of another man in our bed,” he tweeted. “But yes when ur girl leaves u after u spent 100K on her body to get done and then leaves u after have a baby girl who is only a few months … Just sad. Loved Chyna as my wife and accepted all the wrong she did and continued to ride for her and remain Loyal to her. Never did I cheat. But she couldn’t remain loyal and cheated and f----- way too many people and she got caught and now this is all happening and it’s sad. We had a beautiful baby girl that was the best thing that’s happened to me and soon as that baby was born Chyna was out. Soon as kylie and tyga broke up Chyna was over the game. She had a baby out of spite and I’ll never view her the same. I truly thought Chyna wanted to be a family and that’s why I was so loyal to her but I learned my lesson and everyone else was right.”

The 29-year-old began her professional career as a stripper and later moved to dancing in music videos. She appeared in the music videos for Tyga's "Rack City" and for Nicki Minaj and Kanye West's video for "Monster."
