Lisa Rinna Unleashes On Hollywood'S Rudest In Fiery Memoir

Lisa Rinna is not holding back! In her forthcoming memoir, "You Better Believe I’m Going To Talk About It," the former "Real Housewives of Beverly Hills" star is dishing out the dirt on some of the rudest celebrities she’s encountered. Mark your calendars – the book drops on March 12, and it's already available for pre-order!

In a juicy snippet shared by PEOPLE, Rinna names and shames Dionne Warwick, Star Jones, Garcelle Beauvais, Sutton Stracke, Denise Richards, Andy Cohen, Robert Kelker-Kelly, and even the fashion mogul Anna Wintour. It seems like no one is safe from Rinna's sharp tongue.

Rinna takes us back to her days on "Celebrity Apprentice" in 2011, where she claims to have had a less-than-pleasant encounter with Dionne Warwick. Describing Warwick as a "nasty piece of work," Rinna shares how their first meeting involved a rather brusque demand for a Pepsi.

“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!’” Rinna recalls.

And the drama doesn’t stop there. Rinna accuses Star Jones of throwing her under the bus during the second episode, but in true Rinna fashion, she manages to find a silver lining, thanking Jones for preparing her for her future stint as a Beverly Hills Housewife.

Lisa Rinna Slams RHOBH Cast Members

Rinna also goes after some of her former "Real Housewives" co-stars. She didn't mince words when describing Garcelle Beauvais as "fake from head to toe" and a "huge disappointment." Sutton Stracke and Denise Richards weren't spared either, both being labeled as "narcissists."

Even Bravo exec Andy Cohen wasn't immune to Rinna's wrath. She criticized him for using private texts between them in his own memoir. Rinna’s grievances extend beyond the Housewives cast too.

Rinna also had some choice words for Robert Kelker-Kelly, dubbing him the "biggest bully in Hollywood." And she didn’t shy away from expressing her frustration with Anna Wintour for repeatedly snubbing her, although she notes that this behavior has recently ceased.

Get ready for a rollercoaster of revelations as Rinna’s memoir promises to be a tell-all that spares no one.
