EXCLUSIVE! Paris Wants Doug Back — Has Been Calling Him Non-Stop After Hearing He Might Be Dating Miss USA!

Breaking up isn’t easy to do — and Paris Hilton just can’t seem to let her former BF go!

Paris Hilton is NOT reading her break-up handbook. The heiress is pulling the ultimate no-no and has been calling her ex-boyfriend, Doug Reinhardt, non-stop after hearing he might be dating Miss USA, Rima Fakih!

“Paris is furious!” a source close to the blond bombshell tells HollywoodLife.com exclusively. “She was absolutely freaking out in Cannes when she heard Doug, 25, was talking to Rima. She’s been constantly contacting him and wants him back!”

Unfortunately, although the the former Hills hottie tells he’s happily single, he also appears to be over his former girlfriend of fourteen months, and has been ignoring her calls. Ouch.

Reports our source, “Her mom [Kathy] has been consoling her. Doug is just over it.”

Don’t worry, Paris! There are PLENTY of other fish in the sea!
