Lips have always been a talking point for Lisa Rinna, and now they’re at the center of her latest revelations. In her new memoir, the 62-year-old actress and television personality has not only named Hollywood’s “biggest bully” but has also spoken out about some of the rudest celebrities she has encountered throughout her career.

Reflecting on her experience during the 2011 season of “The Celebrity Apprentice,” Rinna didn’t hold back when discussing her interactions with fellow contestant and iconic singer, Dionne Warwick. According to Rinna, Warwick was less than pleasant to work with, describing her as “a nasty piece of work.”

Rinna recounted an early encounter during a task where they had to create their own pizza. Warwick, she claimed, barely acknowledged her presence but demanded, “Go get me a Pepsi!” Despite the abruptness, Rinna complied, only to feel betrayed later when she suspected Warwick of plotting her elimination from the show.

The actress went on to express her distrust of the other women on the show, particularly singling out Star Jones as another figure she had difficulty working with.

‘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,’ she said, referring to Warwick helping to eliminate her on the show.

Rinna also said that she ‘couldn’t trust any of the women’ on The Celebrity Apprentice, before taking aim at Star Jones.

Recalling her stint on The Celebrity Apprentice in 2011, Rinna said that the legendary singer, who was also competing on the season, ‘was a nasty piece of work’

‘I’d like to thank Star Jones for being such a twat, because her viciousness prepared me for my future as a Beverly Hills Housewife.’

‘I’m not sure I’d ever experienced woman-on-woman hate crimes before that,’ she added.

Real Housewives of Atlanta star Nene Leakes also clashed with both Jones and Warwick during her time on the NBC competition series.

Rinna later returned to the franchise in 2013 for the All-Star Celebrity Apprentice, which was won by country singer Trace Adkins.

Daily Mail has contacted reps for both Dionne Warwick and Star Jones.

Rinna’s new memoir, You Better Believe I’m Gonna Talk About It, sees the actress spilling all kinds of tea, from her personal life to her professional.

She admits to being snubbed by Anna Wintour multiple times, but says that the legendary Vogue editor finally said ‘hi’ to her at a Balenciaga fashion show recently.

She also blasted her former Days of Our Lives co-star Robert Kelker-Kelly, calling him ‘horrible’ and claiming that he made her life ‘a living hell’.

Rinna holds very little back in her new memoir, You Better Believe I’m Gonna Talk About It, including details about her sex life with husband Harry Hamlin.

The former Real Housewives of Beverly Hills star has been married to the actor, 74, for almost three decades, and she swears that things are still just as hot as ever between them in the bedroom. 

‘The sex is still great because we’re still really attracted to each other,’ she boasted in the book. 

‘Even if we don’t do it as often, when we do, it’s as good as it’s ever been,’ she continued.

‘After all these years, Harry and I still feel like a team.’ 

You Better Believe I’m Gonna Talk About It isn’t the first book containing tidbits about Rinna’s sex life.

In her 2009 self-help book Rinnavation: Getting Your Best Life Ever, Rinna shared a tutorial about how to perform oral sex using one of her signature tricks.

Her daughter Delilah Belle later revealed in an episode of The Real Housewives of Beverly Hills that the book ‘taught’ her how to have sex. 

‘I was like 12 when I said this,’ Delilah said. ‘It literally teaches you how to give head.’

Delilah’s younger sister Amelia Gray then added, ‘Very precisely.’

A mortified Rinna responded, ‘I never thought in a million years that my own children would read the book.’

Rinna has been all over the media in recent weeks thanks to the release of her new memoir and her stint on The Traitors.

The actress holds nothing back in the book, including exposing Hollywood’s ‘biggest bully’ and dishing the dirt on her former RHOBH co-stars.

‘Publishing this book is my way of speaking my side without anybody editing me out. And listen, I don’t hold back in this book. I definitely don’t,’ Rinna said

She even slammed her former boss Andy Cohen, blasting the TV host for exposing her private text messages in his own memoir.

Cohen later publicly apologised to Rinna when she appeared on Watch What Happens Live last week. 

In an interview with Cosmopolitan earlier this month, Rinna explained why she chose to write her book and include Cohen.

‘It’s about telling my side of the story more than anything. I’m too old to settle scores at this point,’ she reasoned.

The star added that RHOBH ‘never showed me for who I really am. And I had a bone to pick with that.’

‘Publishing this book is my way of speaking my side without anybody editing me out. And listen, I don’t hold back in this book. I definitely don’t,’ she warned.

Rinna has since made amends with Cohen, revealing on SiriusXM that she’s ‘fine with the guy’ now.
