Showbiz Spy reports: The pair recently got back together after they split following reports Kristen cheated on Rob with married director Rupert Sanders.
Rob and Kristen have been putting on a united front in recent days and are, seemingly, determined to prove to the world their romance is back on track.
They have been pictured together in bars and with friends, and today will make their first joint television appearance since their split.
But insiders have speculated about whether the reunion is genuine or just a “showmance” designed to ensure Breaking Dawn – Part 2 is a box office hit, according to Britain’s Daily Mail newspaper.
Many believe industry bosses now want fans to focus on the film rather than the couple’s off-screen rift.
“This has come as a big surprise. New Line [the film studio behind Twilight] feel that a joint TV appearance will ease the impact on fans of their red carpet debut but not diminish the publicity,” a source said.
“In recent days Rob and Kristen have really shown their friendship is back on track. They are comfortable around one another and that inspired this brave move.
“Where they go as a couple after this still has to be seen.”
Recent reports claimed Rob is still having a tough time trusting Kristen.
“Kristen is working hard to try and force the relationship into what it was before,” a source said.
“But the truth is, she’s going to have to take it slowly with Robert because he’s still having trouble trusting her again.
“For him to carry on like nothing happened is very hard. Kristen is eternally sorry for cheating on him and he has forgiven her — kind of.
“The problem is he can’t forget her infidelity. Kristen claims that she never actually slept with Rupert Sanders, but Robert still has that nagging feeling of doubt that she did.
“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.”
