The-Dream, a singer and producer who has worked with Beyoncé, Rihanna and others, was hit with a sex trafficking lawsuit Tuesday (June 4) that accuses him of subjecting a young songwriter to an “abusive, violent, and manipulative relationship” that included an alleged incident of rape.

In a lawsuit filed in Manhattan federal court, Chanaaz Mangroe claims the producer (Terius Gesteelde-Diamant) used promises of career advancement to lure a “young and vulnerable artist” into “a prolonged nightmare” filled with “violent sexual acts.”

“Over more than a year, Ms. Mangroe experienced trauma that she has still not recovered from—she is broken as an artist, constantly afraid for her physical safety, and plagued by reminders of the violence and control she experienced at the hands of Dream, who has continued his successful career unscathed by his horrific acts,” her attorneys write.

In addition to numerous allegations of violent sex, the lawsuit includes an allegation that The-Dream raped Mangroe in May 2015. Her lawyers say he pinned her down inside a sprinter van, started “forcibly having sex with her” and choked her so intensely that she potentially lost consciousness.

Representatives for The-Dream did not immediately return a request for comment on Tuesday.

In addition to five studio albums of his own, The-Dream has credits on a wide range of hits, including Rihanna’s 2007 smash “Umbrella” and Beyonce’s 2008 chart-topper “Single Ladies (Put a Ring on It).” He’s also worked with Britney Spears, Justin Bieber, Kanye West and numerous other stars.

Mangroe, a native of the Netherlands, claims that The-Dream reached out to her in 2014 when she was just 23 years old and working in the United States on an international visa. After she sent samples of her work, she says he invited her to Atlanta to work with him and his producing partner, Tricky Stewart.

Over time, her lawyers say The-Dream “used his age and influence in the industry to manipulate the young artist into believing that she needed him to be successful.” They say he promised to help her secure a visa extension, sign a record deal with a major label and even offered her a chance to open for Beyonce’s upcoming tour.

But in reality, her lawyers say The-Dream “used Ms. Mangroe for his base desires, which manifested in violent sexual acts and vicious psychological torture.” In addition to the alleged rape, they say he frequently subjected her to violent choking during sex, “berated” her during sex and used recordings of their sex to “threaten Ms. Mangroe into silence.”

“Nearly a decade later, Ms. Mangroe is still putting the pieces of her life back together, but she knows that without speaking up about what Dream did to her, she will never be able to heal from the harm he has caused,” her lawyers write. “She therefore brings this lawsuit to speak up for herself and other female artists who have been tormented by powerful and selfish men in the recording industry.

In addition to The-Dream, the lawsuit also names Sony Music’s Epic Records as a defendant, arguing that the producer’s “depraved behavior” was facilitated by the company. The lawsuit claims Epic “benefited from facilitating his behavior to the extent it kept their relationship with the talented musician viable and ensured continued profit from his work.”

Reps for both Epic and parent company Sony Music did not immediately return requests for comment on Tuesday.

The lawsuit was filed by Douglas Wigdor, a New York attorney known for representing alleged sexual assault victims. Wigdor’s firm has filed numerous abuse cases against music industry figures in recent months, including the bombshell case against Sean “Diddy” Combs filed by his ex-partner Cassie.
