A source told the National Enquirer magazine: "Britney would love to have Justin back. They still talk a lot and she's been telling friends for months about how good Justin was for her."
It has also been alleged that Britney, 25 - who has two sons, 16-month-old Sean Preston and four-month-old Jayden James, with Kevin - started dating model Isaac Cohen in attempt to make Justin jealous.
The source added: "Britney gets an ego boost by parading her piece of eye candy around!
"Britney hopes Justin will think more of her now she's been seen with a successful guy like Isaac, because she isn't hanging out with a loser like Kevin anymore. She wants to prove she can still land a good-looking, desirable guy."
Since splitting from Cameron in December, Justin has been romantically linked to Scarlett Johansson.
