Initially it was believed that Jason Derulo and Jordin Sparks' split in September, after dating for three years, was not hostile and the two stars would remain amicable. Well this didn't apply to the 'American Idol' alum as she has just slammed her former love in a newly released diss track.

"Feeling like I have to get all of this off my chest / I know you are sitting there thinking 'What is she going to do next?'" she sings. "Remember I deleted all my other guys' numbers out my phone for ya? / Remember when you broke your neck and I had to wash your back for ya? You probably don't remember half of the s--t that I did for ya."

"You didn't really f**k with me way back then, but how bout now?/ 'Cause I'm up right now and you suck right now," she continued.

Shortly after their split, Derulo seemed to be in good spirits when he first spoke of the separation on Sept. 25. During an interview with KDWB in Minneapolis he said, "Yeah, everything is cool, man," when asked if they would still remain friends. "It's not a bad situation. You know, it's not one of those kinda things."

Sparks also played down drama between the two while speaking to Today's Hoda Kotb and Kathie Lee Gifford on Sept. 29. "I'm good, actually," she said. "I read this quote [yesterday], and it said, 'When something unexpected happens in your life, or you think something bad happens, just say 'Plot twist!' and move on.'"
