Los Angeles, Sep 1 : Actor Robert Pattinson has become more conscious about his looks as he knows he is going to be photographed wherever he goes.

The 27-year-old admits he never used to care about whether he looked presentable or not, until he became an A-list star, reports contactmusic. com.

Quizzed whether he thinks he's good looking, Pattinson said: "It depends, sometimes. But I'm weird about my looks. Once you get photographed a lot it changes you. I remember when I first did 'Twilight', I didn't care about how I looked - there was less pressure!"

"(Now) every time I appear somewhere, I think, 'I don't know how many more times I can do this.' Dressing up to go somewhere and be looked at - I get so nervous. Up until the second I have to leave, I'll get changed a million times," he added.(IANS)
