Robert Pattinson worries about his looks

"Twilight" star Robert Pattinson has revealed that stardom has made him conscious to look good whenever he steps outside his home.

The 27-year-old actor says he worries about his looks now as he knows he would get photographed everywhere he goes, reported Contactmusic.

"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," Pattinson said.

"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.
