Luann, 53, returned to the Atlantic City hotspot for a sold-out performance of her #CountessandFriends Cabaret Show.
The mother-of-two looked absolutely stunning in three sparkly Jovani gowns during her time on stage.
“Borgata feels like home to me almost because I did my music video for Chic C'est La Vie here," Luann shared backstage. It’s such a great room, great ambience, and the crowd is always fantastic at Borgata."
Throughout the evening, Luann read stories from the past 30 years from a bejeweled, homemade diary. This included her own personal take on her divorce from ex-husband Tom D'Agostino to the horrific boat ride she and her RHONY costars endured in Cartagena last year.
During an audience Q&A, someone asked Luann who her least favorite RHONY costar is. "I would say Alex McCord," she replied. "Oh my god and Simon (van Kempen), oh my god!”
Alex and Simon were part of RHONY for its first four seasons. The mother-of-two was given the boot along with Jill Zarin, Cindy Barshop and Kelly Bensimon before season five began filming.
