Blac Chyna says she is 'devastated' after Rob Kardashian posted explicit photos online.

Blac Chyna has spoken publicly for the first time after Rob Kardashian, her ex-fiancé and father of her daughter, Dream, shared sexually explicit images of her online in a devastating act of revenge.

Kardashian, 30, shared the images on social media last week, alongside accusations that Blac Chyna cheated on him with multiple men, used his family name for money and fame, and had been neglecting their young daughter.

In a new interview with Good Morning America, which aired just hours before the 29-year-old was granted a temporary restraining order against her ex in a Los Angeles court, Blac Chyna said she was “devastated” after learning that her private images had been shared with millions of people.

“How could somebody post these pictures of me?” she told the morning news program. “This is a person that I trusted. I just felt…betrayed.”

She also said there was no truth to rumours that she had "liked" the sexually explicit pictures on Rob's social media before they were removed by Instagram.

"I didn't 'like' any of the photos," she said. "I actually had Robert Kardashian blocked from my Instagram."

Blac Chyna has hired attorney Lisa Bloom, who famously represented Mischa Barton in a revenge porn case earlier this year, to pursue legal charges against her ex.

"The moral of the story is he doesn't respect me," she said, adding, "If you can't respect me, you have to respect the law."

"In California, revenge porn is a crime, a civil wrong and a form of domestic abuse," said Bloom, noting that any explicit photos Blac Chyna may have posted in the past has no relevance to her case against Kardashian.

LISTEN: According to science, we only watch the Kardashians when we're happy.

"Any explicit photos that she may have chosen to post in the past, that's her choice," Bloom said. "This is like saying a woman can't be raped if she previously chose to have sex with someone. It's her body, it's her choice, each and every time."

Blac Chyna denied, too, that she used Kardashian or his family as a way to gain notoriety. "I was already Blac Chyna before the Kardashians," she said.

"Nobody was out to make a baby out of spite."
