The first clip of the new Twilight sequel Eclipse has been unveiled.

The ten-second trailer opens with stars Robert Pattinson, 23, and Kristen Stewart - who play vampire Edward Cullen and Bella Swan - embracing in a meadow.

There's also a glimpse of a topless Taylor Lautner, 18, as werewolf Jacob Black.

Eclipse focuses on the love triangle between the three characters.

‘I'm going to fight for you until your heart stops beating,' Jacob tells Bella in the promo.

The Twilight Saga: Eclipse is out in the UK on 9 July.
