Kristen Stewart makes a leggy appearance supported by boyfriend Robert

In a sure sign that they are becoming more comfortable with letting the public in on their relationship, actors Kristen Stewart and Robert Pattinson stepped out together in Cannes on Wednesday.

The vampire idol was lending support to his girlfriend and Twilight co-star at the premiere of her new film On The Road.

But he was careful not to steal the limelight, stepping back to let his love pose for the cameras with her colleagues.

And the pair were later spotted kissing passionately at an after party.

Robert was undoubtedly proud of Kristen, who looked stunning in a cream, floor-length Balenciaga gown.

With its embroidered halter neck and thigh high split, the gown was a daring choice for the starlet, who usually favours more gothic looks.

The 22-year-old teamed the striking, leg-baring dress with her trademark tousled tresses and skyscraper heels.

She was joined by glamorous co-star Kirsten Dunst, who showed off her gorgeous curves in a fuchsia Christian Dior column, teamed with a sparkly Louis Vuitton clutch.

They walked Cannes’ famous walkway with other stars including model Milla Jovovich, who played up her feminine side in a lilac, floral embellished gown.

And Michael Buble’s pretty Argentine wife Luisana Lopilato, who is the face of lingerie brand Ultimo, also turned up looking lovely in lemon.
