Kristen Stewart and Robert Pattinson will reportedly be attending the Cannes International Film Festival together.

The pair have tried to keep their relationship under wraps since reports they started dating after meeting on the set of Twilight. However, it seems they will be stepping out in public together for the French festival in May.

The two will be showing support for each other's latest films, including Robert's Cosmopolis, sources told E! Online.

Kristen is also reportedly planning to bring her mom Jules Mann-Stewart along, for the premiere of her new movie On the Road.

The actress is set to raise eyebrows playing the role of Marylou as she appears topless in one scene of the adventure film.

The news comes after it was announced that Robert and Kristen are reshooting scenes for the final instalment of the Twilight franchise.

The couple, who play Edward and Bella Cullen in the vampire franchise, will be returning to the Canadian set to film ''technical'' scenes.

However, director Bill Condon has insisted there will be no new scenes or dialogue.

''A film is a lot like a puzzle, with each piece - each shot, no matter how brief - needing to fit exactly with the ones around it," he wrote on Facebook.

''We're not shooting any new scenes or dialogue, just some technical work with some of our cast and stunt actors.

''I am really looking forward to being back on set with some of the friends I've made on my Twilight journey... And yes, Rob and Kristen will be there too, to pop in those gold contacts one last time.''

The Twilight Saga: Breaking Dawn - Part 2 is scheduled to be released worldwide in November.
