Robert Pattinson has urged Hollywood newcomers to take care of their mental health.

The 29-year-old actor, who found fame as a teen heartthrob in the 'Twilight' franchise, believes his personal growth stopped at 22 because he became a household name at such a young age.

He explained: ''It was amazing, but a little demanding psychologically. It only becomes clear much later though. My advice would probably be: take good care of your mental health. If you get famous as quickly as I did, your personal growth stops suddenly.''

However, the star - who is engaged to singer FKA Twigs - has now regained control of his personal life in his late twenties.

He added to Germany's Teleschau magazine: ''I stopped growing at 22 back then and I was in shock for four years. It's different now. My personal and professional development path is slowly emerging. That makes me happy.''

Among the perils of fame, Robert admits it can be ''stressful'' to constantly have paparazzi pictures taken of him.

The actor - who plays photographer Dennis Stock in new movie 'Life' - lamented: ''Today there is such an over-saturation of pictures and because of that the pictures have to become more and more extreme in order for people to look at them. A beautiful picture of a celebrity doesn't do it anymore, one has at least look drunk in it.

''It's still stressful for me, but it also depends on the overall mood. If you are in a good mood you don't really mind, but if you are in a bad mood it affects you more than it should. You run the risk of circling around yourself. You start to think, 'How will I look in the next picture?' even when no one is taking a picture.

''It drives you crazy sometimes. Fortunately it has gotten a lot calmer for me.''
