Paris Hilton has surprised her fans by using her real voice in a new TV interview to promote upcoming documentary This Is Paris, which gives fans an insight into the private life and upbringing of one of the world's first true reality stars.

During an interview with Today and Sunrise Hilton used her real voice as she chatted to reporter Edwina Bartholomew.

“This entire time, I have been playing a character, so the world has never truly known who I am. The real me is someone who is actually brilliant. I’m not a dumb blonde, I’m just really good at pretending to be one,” she said.

Hilton was then asked why she had to decide to come forward with details of her life. She responded:

“I feel like I’ve been through so much … there’s so many misconceptions and preconceived notions about me.

“I don’t want to be remembered as some airhead. I want to be respected for the businesswoman I am.”

And fans were quick to respond to Hilton using her real voice during the interview.

"I’m glad to hear Paris dropping the baby voice. She’s a grown woman and can finally be her authentic self." One Twitter user wrote.

Hilton also recently opened up about her 2004 sex tape scandal, describing the experience as "traumatizing".

The 39-year-old socialite, businesswoman, and TV personality revealed in an interview with the New York Times that the tape - which was made with her then-boyfriend Rick Samolon back in 2001 - was a "private moment", and was never intended to be seen by audiences.

Speaking to the outlet, Hilton said: "To have that come out. Such a private moment, and for the whole world to be watching it and laughing like it’s some sort of entertainment, was just traumatizing."

In the new documentary, Hilton, 39, states that the emotional and physical abuse she says she suffered as a teenager at the Provo Canyon boarding school in Utah played a role in her relationships later in life.

"I had become so used to [abusive behavior] at Provo, that it made me feel like it was normal," she told PEOPLE. Those relationships, with five ex-boyfriends, seemed to have common themes. "They all seemed like such nice guys and then the true colors would show," Hilton explained. "They'd get jealous, or defensive or try to control me. And there there would come a point where they would become physically, verbally and emotionally abusive."
