New York- "Manhattan Madam" Kristin Davis kept her lips zipped Saturday as discrepancies emerged in her story of a sexual assault in the hallway of her Queens apartment building.

"I'm late for my job," she snapped at a Daily News reporter.

Police sources said the unhappy madam reeked of alcohol Friday night and revised her story several times after calling 911 to report the attack.

In her initial call to police, the 32-year-old Davis said a man with a bottle of vodka was buzzed into her nondescript Astoria building and made off with her wallet. She didn't mention a sexual assault.

Davis later told cops from the 114th Precinct in Queens that the man groped her before leaving, describing the attacker as a black man, the police sources said.

In a second police interview, she said the assailant was either Asian or Hispanic.

Eventually, Davis told police she could not identify her attacker.

After the alleged attack, Davis told The News that she had let the man inside the building when he offered to help her carry groceries inside.

Neighbor Gladys Suarez, 70, who lives one floor above the former owner of now-shuttered Wicked Models escort service, remembers hearing a commotion after Davis came home Friday night. She didn't recall seeing any grocery bags.

Suarez found a distraught Davis sitting against a wall in the narrow second-floor corridor, fumbling through her purse for a cell phone. Her neighbor smelled of alcohol, Suarez said.

"She kept crying and screaming, and she said somebody from outside had brought her there and dumped her and left her there," Suarez said.

Steppin' Out editor Chaunce Hayden said Davis called him Friday night before reporting the incident to police. She was slurring her words, although he initially chalked it up to her shaken state.

"With a controversial figure like this, a lot of things run through your head," Hayden said yesterday. "Your guess is as good as mine. It's up to the police to decide what's going on."
