Spencer Pratt feels he's been "misrepresented for most of [his] life"

Speaking to People, Spencer explained: "I've been misrepresented for most of my life - and honestly? That worked for a while. But the real story is way more interesting than the fiction, which is why I'm finally telling it, no holds barred, in my own words."

Spencer - who has been married to fellow reality star Heidi Montag since 2008 - hopes the public will now see a different side of his personality through his upcoming memoir.

The TV star said: "I poured everything I have into this book, sharing all the secrets, and I couldn't be more thrilled to share it with you."

The memoir promises to reveal the "untold truth" behind Spencer's life.

The book's synopsis explains: "Now, for the first time, Spencer reveals the untold truth behind the spectacle - a darkly comedic, unflinching and often surreal confessional from a TV villain who's finally broken character for good."

Meanwhile, Heidi recently described herself as a "trailblazer" in the entertainment industry.

The 38-year-old reality star was widely criticised in 2009 after undergoing ten cosmetic surgery procedures in one day - but Heidi thinks it was "important to be honest" about her cosmetic surgeries.

Asked about her act of honesty, Heidi told The Independent: "I definitely was breaking the barrier and the fourth wall of what everyone was secretly doing in Hollywood.

"Part of being a trailblazer is when you are the first one to do something, you're usually the most criticised for it. That's something I can accept because I never want to be a liar; that's not the way that I'm built."

Heidi doesn't have any regrets about being so honest.

She explained: "I wanted to tell the story of, hey, this is what I did and what a lot of people do; to break that facade and that mirage of what's going on in Hollywood."
