As records go, this one is a nail-biter.

A Las Vegas singer stepped out in New York yesterday as the proud owner of the longest fingernails in the world.

Chris "The Dutchess" Walton made it into the 2012 Guinness Book of World Records for the first time for having nearly 20 feet of nails on both hands.

"It's kind of like a body part that I was born with, now I don't know what I would do without them," the 45-year-old said.

"I'm pretty sure one day I will cut them, but I can't see it in my head because I'm so used to having them.

"It's like a leg, I wouldn't just chop it off so it's gonna take some thinking."

"The Duchess," a mother of six girls and grandmother of three, says she started growing her nails 18 years ago by accident.

Now the nail on her ring finger is the length of the average human arm, her left pinky nail is almost the height of a New York City fire hydrant, and the middle fingernail on her left hand is as long as two Nathan's hot dogs.
