RHONY star Luann de Lesseps was reportedly kicked out of a gay piano bar after allegedly getting drunk and acting inappropriately.

Page Six reports that Luann “took over the mic” and started to sing. When the crowd booed her, she allegedly yelled “f–k you.” She was kicked out of the bar.

“She monopolized the piano, but that isn’t how it works, you sing [one song] and move on,” a source said. “Luann thought she was doing her act. She tried to sing [her own song] ‘Money Can’t Buy You Class,’ but they didn’t know it, they know standards.”
