Stewart 'supports Pattinson at premiere'

Kristen Stewart reportedly turned out to support Twilight co-star Robert Pattinson at the premiere of his new film last night.

According to Access Hollywood, the actress arrived alone and walked the red carpet at a New York screening of romantic drama Remember Me.

She posed for photographs by herself, while Pattinson posed with co-stars including Emilie de Ravin.

The on-screen lovers have previously remained coy about speculation that they are dating in real life, although they were allegedly spotted holding hands at an airport last November.

Remember Me is released in the US this month and in the UK next month.
