The film premiered in LA on Monday night, where hundreds of teenage girls turned up to check out the stars on the red carpet.

Kristen Stewart wore a long purple and black sequinned dress, split to the thigh, while British actor Pattinson wore a grey suit.

Breaking Dawn is likely to be another box office smash for the Twilight franchise, helped by the fact that lead characters Edward Cullen (Pattinson) and Bella Swan (Stewart) will take part in their first sex scene. The actors are a couple in real life.
