LONDON: Robert Pattinson only signed up for acting classes to meet girls.  The ‘Twilight Saga’ actor - who played Edward Cullen in the vampire franchise - admits he was ‘’horribly shy’’ as a youngster, but his father convinced him to train as an actor to overcome his nerves and meet a potential girlfriend.  He said: ‘’I was horribly shy. One day in a restaurant, my dad overheard a group of pretty girls talking about their acting classes. ‘’He told me, ‘Sign up, you might meet someone!’ I did it ... and it worked pretty well!’’  He admits he still has to fight for the roles.–ES
