Yoselyn Ortega, the Manhattan nanny accused of killing the two young kids in her care, tried to paint her employer Marina Krim, in a negative light to cops during her interrogation at the weekend, Breaking Celebrity News is exclusively reporting.

"Yoselyn implied there was a lot of strain between she and Marina in the days leading up to the murders of little Leo and his older sister Lucia," a law enforcement source told Breaking Celebrity News exclusively. "The detectives were amazed at how cavalier Yoselyn was during parts of her interrogation. Yoselyn complained that she thought she should of been making more money and that she was being underpaid for additional duties than what she signed up for. When Yoselyn began working for the Krims they also had a housekeeper and Yoselyn said that she didn't like the way that Marina spoke to her. It was obvious Yoselyn was trying to portray her in a bad light."
