Former Real Housewives of Beverly Hills star Camille Grammer has been granted a temporary restraining order against her boyfriend Dimitri Charalambopoulos, whom she claims beat her in a hotel room days after she had a surgical procedure to remove cancer.

In court papers filed Tuesday and obtained by ET, Grammer, 45, alleges the abuse by her boyfriend of two years happened  earlier this month in a Houston hotel where she was recovering from a hysterectomy after being diagnosed with early stage endometrial cancer.

The reality star said the abuse was triggered by an argument that started on October 16 when she was awoken by the cell phone of Charalambopoulos, which was vibrating with text messages and phone calls from another woman. She alleges that her boyfriend then became verbally abusive and "grabbed me by the hair, twisted it around his hand and repeatedly pulled my head into the bed and its headboard."

In the court papers, she describes an escalation of the alleged violence, saying Charalambopoulos also "succeeded in pulling out swaths of my hair and gave me a large, painful contusion on the side of my head" and "squeezed my nose between his fingers and pushed upward forcefully, meanwhile covering my mouth in an attempt to silence me and to prevent me from breathing." She added: "I experienced great pain in my nose and became afraid for my life as a consequence."

Grammer said the assault continued for 40 minutes to an hour, while she "begged him to stop" and threatened to call the police. "He wrestled me on the hotel bed, repeatedly slamming my head and face into the furniture, and eventually he succeeded in completely immobilizing me."

Grammer accused Charalambopoulos of covering her mouth and smashing her cell phone to prevent her from calling the police and said she was only able to get help once he left the room. "I was in shock, bruised, battered, and injured on the bed. I remained there for approximately three minutes after Mr. Charalambopoulos left. Then, I collected myself and mustered my courage to seek help."

Charalambopoulos is expected to respond to the allegations at a court hearing scheduled for November 19 to determine whether Grammer's temporary restraining order should be extended.

In a statement to ET, the Houston Police Department said it responded to Grammer's hotel on October 16 at around 3:30 a.m.after she reported the alleged assault and officers observed that Camille had suffered minor injuries. Houston PD said the investigation is ongoing in its early stages and no charges have been filed.

A friend of Grammer, Allison Dubois, told ET that she's proud that she decided not to just "brush it under a rug," but to take a clear stand. "She's a good role model for young women, all women and men who might be in abusive relationships," Dubois said. "But there's no shame in speaking up and saying no more. This isn't okay, and by Camille sharing her story, it will strike a chord with a lot of people," she added.
