Jordin Sparks has taken a swipe at her ex-boyfriend Jason Derulo in a song.

Jordin discusses looking after Jason, 25, in the aftermath of him suffering a neck injury in 2012, singing: "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?

"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."

Since splitting earlier this year, Jason has conceded that they're not on particularly friendly terms.

Jordin, meanwhile, has remained quiet about their failed relationship for the most part.

But shortly after announcing their split, Jordin said: "I'm good actually. 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.'"
