Kristen Stewart is planning a last-ditch attempt to save her relationship with Robert Pattinson by hot-hoofing it to Australia for a face-to-face showdown with the Brit actor, a source tells Breaking Celebrity News exclusively.

Pattinson, who is in Adelaide filming The Rover, hasn’t been giving Stewart, 22, the attention she wants while he’s been working, the source says, which has left the On The Road beauty contemplating if Robert’s heart is still in it.

But now, with a break in her schedule, she wants to fly Down Under to convince him his heart belongs with her!

“Kristen is planning to travel to Australia to see Robert, she’s missing him incredibly,” the source tells Radar.

“She thinks his interest in their reconciliation is waning the longer they’re apart – so Kristen’s trying to save what they have left.

“Robert’s been busy filming and hasn’t been able to give Kristen as much time as she liked. It’s been especially difficult to stay in touch because of the 18 and half hour time difference between Los Angeles and Adelaide.

“Their relationship is hanging by a thread, so she thinks that visiting him in Oz may help them stay together. That said, I think she may be clinging on to something that isn’t what she actually thinks it was."

As Breaking Celebrity News previously reported, a source said Stewart was considering ending her romance with Robert because she believes he’s no longer committed to dating her anymore.

“The truth is, it’s really over between them, no matter how hard they try to fix it,” the source told Radar.
