Lisa Rinna reveals rudest A-listers she’s ever worked with after exposing ‘biggest bully in Hollywood’

Lisa Rinna has opened up about who she claims are the rudest A-listers she’s ever worked with after exposing the 'biggest bully in Hollywood'.

The 62-year-old American actress has released a new memoir, You Better Believe I’m Gonna Talk About It, a look back at her career and personal life.

Since the book landed late last month (24 February), readers have been picking through its more surprising moments with the TV star sharing plenty of candid stories from over the years. And, clearly, she has no issue name-dropping along the way.

In the book, Rinna reflects on her years on the NBC soap, Days of Our Lives, where she played Billie Reed from 1992 to 1995 before returning to the role several times over the following decades.

The experience was not always pleasant behind the scenes, however, with Rinna claiming that Robert Kelker-Kelly, who played her on-screen partner Bo Brady, made her life 'a living hell'.

According to MailOnline, she wrote: "Behind the scenes, we hated each other. Remember when Kathy Hilton said I was the biggest bully in Hollywood? Not true. Not even close! I have legit stories about the real bullies in this town."

She claimed that Kelker-Kelly was 'one of those bullies', adding: "He made my life a living hell on the set of Days. He was horrible to me. I’d go so far as to say verbally abusive. He was passive-aggressive, manipulative, and played weird mind games."

Rinna further alleged that he would give her the 'silent treatment' if she 'didn’t do what he wanted' in scenes.

Calling him a 'ticking time bomb', the reality TV star continued: "I never knew when I arrived on set each morning if I’d get nice Robert Kelker-Kelly or dark Robert Kelker-Kelly. He was unpredictable, and it was exhausting."

And it's not just Kelker-Kelly who found himself in the firing line, as Rinna has also blasted her former Celebrity Apprentice co-stars Dionne Warwick and Star Jones as the rudest celebrities she’s ever worked with.

She went as far as to label Warwick a 'nasty piece of work', recalling in her memoir: "The first time I met her on a create-your-own pizza task, she barely looked at me but had the audacity to bark, 'Go get me a Pepsi!'"

"And for some reason, I ran off like a simp to get Dionne Warwick a Pepsi. She thanked me by conspiring with her coven to get me canned," Rinna went on, making reference to her early departure from the fourth season of the reality series.

Rinna was later 'fired' from the show, claiming that Jones had a part to play in her departure after she 'threw her under the f*cking bus' in episode two, per News.com.au.

Looking back in the memoir, Rinna said that the competitive atmosphere left her uneasy around the other contestants, writing: "I couldn’t trust any of the women."

She also addressed Jones directly, saying she still values the experience despite the friction.

"Being such a tw*t, because her viciousness prepared me for my future as a Beverly Hills Housewife," Rinna added.
