Robert Pattinson not sure about acting career

London: ‘Twilight’ heartthrob Robert Pattinson is really worried whether acting is his cup of tea."I always think there must be more. I get angry, because I think I’m missing out," he said.

The 23-year-old British actor is also an eager musician and songwriter. And he has plans to release his album some day but he is unable to find time as he is already engaged throughout the year with prior commitments, reports The Sun. "I haven’t been able to do my music for ages. I can’t concentrate on two things at once. I don’t even listen to music when I’m working on a movie," Pattinson said. His next movie The Twilight Saga: Eclipse is slated to release in June this year. ANI
