The Girls Aloud singer reportedly ended her on-off relationship with the 'Desperate Housewives' hunk last week after deciding things weren't working out.
A source said: "Nadine decided to break up with Jesse. She's saying it's just a break but we all know it's not. They've had a very unstable relationship of late and she tried everything to make it work.
"But they want different things in life at the moment and that was the final nail in the coffin."
Jesse and Nadine - whose bandmate Cheryl Cole is battling to save her marriage to soccer star Ashley Cole after he cheated on her with a blonde hairdresser - began dating in February 2006.
They were rumoured to have got engaged last year, but split soon after Jesse entered rehab for alcohol addiction.
But the pair rekindled their romance after realising they couldn't live without each other.
However, just weeks later Nadine and Jesse broke-up again, before getting back together.
They were recently seen house-hunting in Los Angeles and friends were convinced they were about to take their relationship to the next level.
Nadine has now decided she is better off being single and is already making exciting plans without Jesse.
The source added to Britain's Daily Mail newspaper: "She flew to Los Angeles recently and spent the entire trip with her family and girl pals. She even discussed a big girly trip to Las Vegas - without Jesse. She's never really done that before, he used to always be part of her plans. She's well and truly getting on with her life as a single girl."
