The once Hollywood couple Robert Pattinson and Kristen Stewart, who are reportedly rekindling their troubled relationship, looked inseparable at the The Twilight Saga: Breaking Dawn Part 2 premiere at Leicester Square, London on Wednesday.

The couple, who reunited recently after a breaking up following Kristen Stewart's affair with her director, looked very much in love as they walked the red carpet with their hands clutched tight.

In fact, Kristen Stewart looked very sexy in a backless and nude-coloured gown with black laces and Pattinson looked handsome in a navy suit. They were accompanied by their co-star Taylor Lautner.

It looks like Robert Pattinson's mother Clare Pattinson too has forgiven Kristen for cheating on her son a few months ago.

"Kristen and Rob's mom hugged when they saw each other at the after-party. They looked really happy to see each other and spent quite a bit of time talking and laughing. Bill Condon and Rob were also there, but they were talking to each other, and Kristen and Rob's mom were talking to each other," HollywoodLife.com quoted a source as saying.

"Kristen and Rob's mom looked like they have a great relationship. I didn't see any tension between them whatsoever!" added the source.

It may be recalled that the couple parted ways in July after Kristen Stewart cheated on Robert Pattinson with her "Snow White and the Huntsman" director Rupert Sanders, prompting the actor to move out of their shared Los Angeles home. Sanders is married with two children.

Kristen made a shocking revelation in July about her affair with Sanders and issued a public apology for cheating on Pattinson. The 41-year-old director, who is married to actress and model Liberty Ross, also offered an apology for his extra-marital affair.
