Lisa Rinna Exposes Hollywoods Biggest Bully!

 has accused one of her former co-stars of being Hollywood's 'biggest bully' in her new book, You Better Believe I'm Gonna Talk About It.

While longtime fans may have expected the 62-year-old to name one of her fellow divas as the culprit, Rinna confirmed that her worst showbiz encounter actually took place in the early '90s on Days of Our Lives.

Rinna, who played Billie Reed on the soap opera, said that it was her on-screen love interest Bo Brady, played by Robert Kelker-Kelly, who made her life 'a living hell' on the set of the hit series. 

'Behind-the-scenes we hated each other,' she wrote in the book. 

'Remember when said I was the biggest bully in Hollywood? Not true. Not even close! I have legit stories about the real bullies in this town. Robert Kelker-Kelly is one of those bullies,' she continued.

'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.'

She added, 'I had to work with him every day, often half naked to do love scenes. If I didn’t do what he wanted, he’d give me the silent treatment.

'He was a ticking time bomb. 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.'

Rinna was relieved when he abruptly left the show and was replaced by Peter Reckell, who had originally played Bo Brady from 1983 to 1992. 

She then claimed that after his exit, both she and her co-star Kristian Alfonso, who played Kelker-Kelly's other love interest Hope Brady, were provided with a security team from NBC, although she did not think he was a threat and implied that the security unnecessary.

'Suddenly, one day, he disappeared from the Days set. Next thing I knew Kristian and I had our own full-time security detail,' she alleged.

'I wasn't worried about physical harm, but NBC had to cover their ass. We had rent-a-cops parked outside out houses and trailers for three weeks and were driven to and from work.'

NBC declined to respond when reached for comment. Kelker-Kelly has also been contacted for comment.

Rinna played Billie Reed on Days of Our Lives from 1992 to 1995, before quitting the show and being replaced by Krista Allen. 

As for Kelker-Kelly, he remained a successful soap actor for many years, starring in Another World and General Hospital after exiting Days of our Lives in 1995. 

He later left Hollywood to become a professional pilot and flight instructor. 

Rinna's latest book isn't the first time that she's shared her negative experience with Kelker-Kelly.
