The famous "Robsten" duo may have reunited and enjoyed a private smooch or two but that doesn't warrant their presence together for promoting "Twilight Saga: Breaking Dawn Part 2." Judging from the photos and the press releases, Robert Pattinson and Kristen Stewart have taken separate ways in promoting their upcoming flick.

Kristen Stewart hopped on a plane headed to Japan earlier in the week to promote the highly-anticipated end to Stephanie Meyer's best-selling novels, "Twilight." Wearing her iconic scowl, sunglasses and a cap, Stewart arrived at Japan late in the afternoon where she was greeted by her fans. Thankfully, Stewart was feeling up to the weather and stopped to sign some autographs.

Stewart's famous beau on the other hand was unavailable to be in Japan at the same moment. Instead, the 26-year old had headed to Australia to promote the flick. Apart from promoting the film down under, Pattinson also enjoyed a few minutes at a photo shoot in Sydney, Australia.

Given that the couple is promoting the flick separately, are things between the "Robsten" duo still not going smoothly? Earlier reports claim that Pattinson has been a little stiff towards Stewart since their reunion. However, based on the photographs of the couple, things seem to appear alright.

"It's too early for him to fully accept that they're an item again, but Kristen is pushing for them to go back to how they were," explains a source, adding, "But the truth is, she's going to have to take it slowly with Robert because he's still having trouble trusting her again."

Body language experts do somehow agree that everything seems to be alright with the two.

"In pics of Kristen before they got back together, you can feel Kristin's tension. Her face was more sullen and sunken in and she had very tight muscles in her walk . Her head was more down, which is a signal of shame," explains an expert.

"Rob on the other hand was trying to keep that stiff British upper lip," explains the body language expert, adding, "But now he really looks more calm. He usually looks very electric but at the Cosmopolis premiere he seemed more contained."

Well, fans of the couple will just have to wait and see until the big red carpet premiere. Hopefully by then, Robert Pattinson and Kristen Stewart manage to appear all lovey-dovey for the crowd.
