Robert Pattinson 'Nervous About K-Stew Meeting'

Robert Pattinson is apparently "not looking forward" to coming face-to-face with ex-girlfriendKristen Stewart.

According to Radar Online, the actor has been "re-evaluating" his romance with K-Stew while on set of his new flick The Rover in Australia, with Rob apparently arranging a meeting with Kristen in LA when filming ends.

An insider told the website: "Temperatures may have topped 50 degrees at times during filming, but Robert's been happy to be away from Los Angeles.

"The set really is in the middle of nowhere, a good drive from Adelaide, so it's been the ideal setting for him to forget all his troubles and bury himself in his work.

"After filming, Robert's been keen to socialise with the cast and crew and loves being in the outback, away from city life."

The source continued: "It's the peace and quiet he has needed since his relationship woes with Kristen, and the perfect way to re-evaluate things.

"But, with just short of three weeks left of filming, Robert's beginning to get nervous about returning to LA and Kristen.

"He left in frosty circumstances and needs to make a decision on what to do next. Either way, it will involve a big sit down chat with Kristen and that's something he's not looking forward to."

Stewart - who admitted to cheating on Rob with director Rupert Sanders last summer - has apparently been seeking advice from fellow Twilight co-star Taylor Lautner.

The source added: "Kristen has been spending a lot of time with Taylor of late because she's been using him as a sounding board for her relationship with Robert," the source claimed.

"She thinks that he may have some insight in how she should proceed with Robert - and where their relationship is going."

Twilight author Stephanie Meyer previously revealed she feels responsible for the media attention both Rob and Kristen receive.
