Shar Jackson Says Leave Her Baby Daddy Alone!!!

NEW YORK - Shar Jackson, the mother of two of Kevin Federline's children, says the media should stop ridiculing the aspiring rapper, who with his break-up from Britney Spears appears to have an even bigger punch-line target on his back.

"He's such a nice guy," the 30-year-old actress tells "Inside Edition" in an interview that was to air Thursday. "He's made some mistakes but everybody else doesn't have the whole world pointing their finger at their mistakes."

Jackson and Federline, 28, are the parents of a 4-year-old girl, Kori, and a 2-year-old boy, Kaleb. They dated before he became involved with Spears, whom he married in 2004, while Jackson was pregnant.

Spears, 24, filed for divorce on Tuesday. She's seeking custody of their two sons, 1-year-old Sean Preston and Jayden James, who was born Sept. 12. Federline, who's been making the rounds promoting his hip-hop debut, "Playing with Fire," counter-filed court papers Wednesday seeking sole custody and spousal support. Jackson, who starred in TV's "Moesha" in the late `90s, says Federline does not pay child support to her. But, she adds, "He does pay for their school, and they go to a very expensive private school." Celebrity divorces, Jackson thinks, are nothing to celebrate. "I don't understand why people take so much joy in other people's pain."

And speaking of K-Fed, he had this to say during his concert at Chicago's House of Blues a day after Brittney filed for divorce:

According to People Magazine, K-Fraud said the following last night at his "free concert":

Playing the role of a rap Casanova, Federline, who is seeking sole custody of his kids with Britney Spears, leaned into the crowd to touch the hands of women who were reaching toward him. Several songs into the set, he referenced his breakup with Spears. "Hey, I see a lot of fine ladies in here," said the rapper. "You know I'm a free man, right, ladies? You wanna dance with a pimp?" .......Ummmmmm No!!!!!
