The mother of two tots allegedly slaughtered by their nanny six years ago lost her cool in court Friday, screaming “You’re evil!” at her former caregiver as she bolted from the courtroom.

Marina Krim’s wild outburst came as she walked past Yoselyn Ortega in Manhattan Supreme Court.

“You’re evil and you love this! You like this!” Krim screamed as she was escorted out of the courtroom by court officers after she finished testifying in the case.

Ortega — who had sat stone-faced Thursday as Krim recalled in chilling detail how she discovered Lucia, 6, and Leo, 2, with dozens of stab wounds in a bathtub — covered her face with one hand.

Earlier Friday, Krim also blasted Ortega’s lawyer, who was questioning her on cross-examination.

“You’re fishing and she’s a liar! They’re liars!” the mom shouted in front of jurors. Judge Gregory Carro told them to disregard her outburst.

For a second straight day, Krim took the witness stand to recount Ortega’s time as nanny to Lucia, Leo and a third child, Nessie.

She told the 12 jurors that the Dominican Republic-born caregiver began acting strangely leading up to the October 2012 carnage.

“I knew she was going through a rough period. She was just not her normal self,” Krim testified about Ortega, who’d just gotten kicked out of her Bronx apartment. “I would say she was distracted. She was more arrogant … She had that smug look to her, like she has right now. It’s disgusting.”

Krim also recalled Ortega’s odd reaction when the mom revealed she had suffered a miscarriage just before Lucia and Leo were murdered.

“When I told her I had a miscarriage, she didn’t say anything. She didn’t give me a hug. She gave me no emotion at all,” Krim testified. “She actually looked mad at me that I had a miscarriage.”

“She’s a narcissist — it’s all about money! It’s all about money!” Krim suddenly yelled. “My hands are numb. Can I go? Oh my God.”
