Lisa Rinna is calling out who she believes is the “biggest bully in Hollywood” in her new memoir, You Better Believe I’m Gonna Talk About It — and it’s not who some fans might expect.
While many assumed she’d point fingers at a former castmate from The Real Housewives of Beverly Hills, Rinna reveals that her most difficult experience actually dates back to the early ’90s on Days of Our Lives.
In the book, Rinna — who portrayed Billie Reed — alleges that her on-screen love interest Bo Brady, played by Robert Kelker-Kelly, made her time on set unbearable.

“Behind the scenes we hated each other,” she writes, pushing back on past claims that she herself was Hollywood’s top bully. According to Rinna, Kelker-Kelly was “horrible” to her, describing his behavior as verbally abusive, passive-aggressive, and manipulative. She claims he played mind games and would give her the silent treatment if tensions flared — all while they were required to film intimate scenes together.
Rinna says the unpredictability was draining, never knowing which version of him she’d encounter on any given day. She recalls feeling relieved when he abruptly exited the series and was replaced by Peter Reckell, who had previously originated the role of Bo Brady.

She further alleges that after Kelker-Kelly’s departure, NBC assigned security to both her and co-star Kristian Alfonso, who played Hope Brady. Though Rinna says she didn’t fear physical harm, she claims the network took precautions, providing temporary security at their homes and transportation to and from set.
NBC declined to comment, and Kelker-Kelly has reportedly been contacted for a response.
Rinna originally played Billie Reed from 1992 to 1995 before leaving the soap. Kelker-Kelly went on to appear in series like Another World and General Hospital before eventually stepping away from acting to pursue a career as a pilot and flight instructor.

This isn’t the first time Rinna has spoken critically about her former co-star. In a 2015 interview with Bravo, she admitted they “hated each other with a passion,” adding that their off-screen animosity may have fueled the intense chemistry viewers saw onscreen.
Following her soap opera run, Rinna joined Melrose Place for its final seasons and later returned to Days of Our Lives multiple times, including appearances in 2002, 2012, 2018, and the 2021 spinoff Days of Our Lives: Beyond Salem. Most recently, she appeared on season four of The Traitors.
