Lisa Rinna Slams Former ‘Celebrity Apprentice’ Costar Dionne Warwick as ‘a Nasty Piece of Work’

Lisa Rinna, hot off her dramatic turn on The Traitors, is speaking candidly about the meanest celebrity she’s ever worked with.

Despite having intense beef with both Rob Rausch and Colton Underwood on the latest season of Peacock’s hit competition series — which saw her go up against a castle full of big personalities from the reality TV world — Rinna, 62, says the worst celebrity she worked with was back in 2011 when she was on The Celebrity Apprentice.

It turns out singer Dionne Warwick really rubbed her the wrong way during their time on the show. In her new memoir, You Better Believe I’m Gonna Talk About It, Rinna calls Warwick a “nasty piece of work,” per the  Daily Mail.

“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 writes.

“And for some reason, I ran off like a simp to get Dionne Warwick a Pepsi,” she added. “She thanked me by conspiring with her coven to get me canned.”

Rinna was referring to Warwick being a major part in her eventually getting eliminated from The Celebrity Apprentice in 2011. However, she made enough of a lasting impression to be invited back to All-Star Celebrity Apprentice in 2013.

While she named Warwick as the worst celebrity she’s ever encountered, she apparently also has some choice words for Star Jones, who was also on her 2011 season.

“I’d like to thank Star Jones for being such a t**t, because her viciousness prepared me for my future as a Beverly Hills Housewife,” she wrote, adding, “I’m not sure I’d ever experienced woman-on-woman hate crimes before that.”
