The mother of a Brooklyn woman stabbed to death by her best friend in a fight over diaper money tore into her daughter’s killer today as the friend was sentenced to 15 years behind bars.

“There’s a special place in hell for her for what she did,” said Nicole Colter-Henry, who cried as killer Kayla Henriques, 20, was sentenced for killing Kamisha Richards, 22, in an East New York apartment in 2011.

“I really don’t feel like she has any remorse at all … But karma is something. God sits high but he looks low.”

Henriques — who looked down and shook her head, “No,” when asked if she wanted to speak — was initially charged with murder and could have gotten life in prison if she was convicted at trial.

Friends and relatives of the two women said after the slaying that the longtime friends had fallen out over money Richardson had lent Henriques to buy diapers for her baby.

Richardson became upset when she learned that Henriques had used the money for something else and had yet to pay her back, according to friends.

The two took their dispute to Facebook, where they traded stinging snipes for two days before Henriques plunged the steak knife into Richardson’s chest.
