According to sources, DiCaprio, who is currently dating model Erin Heatherton, is desperate to rekindle his romance with the Israeli supermodel, the Contactmusic reported.
"Leo is using Erin. She's nice and all, but she'll never win his heart. He hasn't gotten over Bar, and in many ways he never will. She'll always be the one who got away. Erin's playing the perfect low-maintenance girlfriend, but Leo's going to get bored with that fast.
"He loved Bar's feistiness and her ability to stand up to him. She was the only girl who was able to drag him home to play dutiful boyfriend. He wanted to marry her and even considered converting to Judaism for her," a source said.
Refaeli and DiCaprio called it quits in May 2011.
