An aspiring Broadway dancer was found stabbed to death in her New York City apartment Sunday night, police said.

Catherine Woods was discovered face down in a pool of blood on the floor of her bedroom. She had been knifed in the neck and hand, and the room was in "disarray, " police said.

Her boyfriend told cops she was an exotic dancer, police sources said.

But her parents in Columbus, Ohio, told The Post their beautiful 21-year-old daughter was a dancer who had appeared in an off-Broadway production called "Privilege."

Cops said the boyfriend, David Haughn, told them he discovered the body of the petite, dark-haired beauty in the bedroom of their second-floor apartment on the East Side of Manhattan.

The couple's Chihuahua was also in the apartment.

Haughn, a doorman, told cops he had left Woods in the apartment at around 7 p.m. to work on his car, which was parked nearby.

Twenty minutes later, he said, he returned to the apartment and noticed the door was ajar.

He told cops that when he entered the bedroom, he saw Woods, who was wearing a jogging suit, covered in blood and unconscious, and called 911.

"She was on her way to a successful career," said her grieving father, Jon Woods, who is the director of the Ohio State University marching band.

"Catherine was a beautiful girl. Very talented. And I think she had a good future. I think she was chasing her dream, which just ended."

The oldest of three children, she graduated early from high school and moved to New York 31/2 years ago.

The police sources said Haughn, 23, told cops the victim worked at FlashDancers Gentlemen's Club, in Midtown.

But two detectives who visited the club last night with her picture said no-one recognized her, and management said they'd never heard of her.

It was not known how long Woods and Haughn — who also is from Columbus — had been living in the apartment.

"I heard someone screaming. It sounded like a young woman," said Andrew Gold, who lives on the third floor.

Gold said that at around 6:20 p.m., "I heard a scuffle. Then I heard a dog barking. Then nothing.

"It was two screams. A long scream and then a short scream. I heard something fall to the ground."

A neighbor who lives across from Woods said a tenant found another dog belonging to the couple whimpering in the hall.

The neighbor said of Haughn, "I see him every day walking the dogs.

"He's a nice kid."

John Kane, a tenant at the building where Haughn works, said, "He's the nicest guy. I've known him for years. He's a really sweet kid."

Another neighbor said he invited Woods and Haughn to Thanksgiving dinner, but they declined.

He thought they spent the holiday alone.

Residents of the building were shocked.

"It's a very good area," said one. "It's a very low-key building. Nothing happens here."
