"There hasn't been any communication as of late," a source close to Kim tells me. "But that will change once she gets back to L.A."
She plans to work on rebuilding a friendship with her ex-boyfriend once she returns from shooting the second season of Kourtney & Khloé Take Miami, says the insider.
"They have a dog together and stuff at each other's homes. It's not like they're enemies. They will work on their friendship, but it will happen very very slowly."
As for those wondering if this split could be a ratings ploy for the second season of her sisters' show...
"Definitely not," the source says. "This has been a long time coming."
So how have the exes been dealing with their breakup?
Reggie went out Saturday to Hollywood hot spot Drai's with a group of friends, including Brody Jenner, Avril Lavigne, Benji Madden and Chad Ochocinco, but was well-behaved despite his newly single status.
"Girls were throwing themselves at him, but he had security keeping them at a distance," another source tells E! News.
As for Kim, she's been enjoying time with her best girlfriends back in Miami. On Friday, she hit STK with Lala Vasquez, Serena Williams and her sisters, where the girls toasted with champagne. And on Saturday, the girls went yachting, with pictures to prove it.
"She loves having time to spend with her friends, something she wasn't able to do as much because of Reggie's schedule," the original source tells me. "On her off time, she was always flying to meet him."
