Watch out Twi-hards! Robsten romance is likely to heat up once again as powerful couple, Robert Pattinson and Kristen Stewart are reportedly heading for yet another reunion, only this time, it could likely be for good.

A source told Us Weekly asserting that Rob and Kristen may likely “pick up from where they left off” after catching up on August 4.

“They will probably pick up where they left off,” the insider said, according to Us Weekly, as noted in a report by HollywoodLife.com. “Rob is obsessed with her. She’s still heartbroken and she can’t seem to get over him.”

Meanwhile, the HollywoodLife.com also affirmed that Rob has always loved Kristen, pointing the things he loves about his girlfriend of four years.

“Rob loves Kristen and always will,” a source was quoted as telling HollywoodLife.com, according to Entertainmentwise.com. "The thing that Rob loved and admired so much about Kristen is her ability to be absolutely herself and not care what others think. She is fearless, and this is what has always captivated Rob.”

Since their split in May, Rob has reportedly been missing Kristen in his life. Despite the slew of women linked to him in the last three months, there was nothing like Kristen.

No one can replace Kristen and the impact she made in Rob: “She always encouraged him to be fearless. To follow his own path. To believe in himself. To take risks. To do something every day that scared him."

Rob and Kristen first reunited early this month. The "Twilight" hunk’s white Durango car was spotted driving away from Kristen’s place, twice. The first time he went on Thursday, August 1, Kristen was reportedly not home that he was forced to come back on Sunday, August 4.

Both stars are busy working for their current projects: Kristen for "Camp X-Ray" and Robert for "Maps to the Stars." Rob already wrapped up filming in Toronto, Canada on July 23, 2013. But filming for David Cronenberg continues in Los Angeles. Kristen for her part is currently on location shoot for Peter Sattler’s "Camp X-Ray."

The couple missed out on Teen Choice Awards 2013 held last week at the Gibson Amphitheater in Universal City, Calif. on August 11, 2013. Kristen has recently been reported attending the University of California L.A. to study English Literature.

Things are looking up for Robsten romance.
