Rupert Grint thinks fame can be ''dehumanising''.

The 30-year-old actor - who starred as Ron Weasley in the 'Harry Potter' movies - has admitted to struggling with his own fame, saying it's made his life a ''weird existence''.

He shared: ''It's almost like having a split personality.

''Sometimes it can be quite dehumanising to have people just taking pictures of you when you're out. To them, you are just this one thing. It's a weird existence. But that's my life.

''I can't really remember life before it. In a weird way, you become blase about it. It becomes normal and you adapt.''

Rupert explained that finding stardom as a child has also led him to develop a peculiar relationship with his own age.

Speaking to the Independent, he said: ''I don't feel like I'm 30 at all. I have quite a weird relationship with age, because of that period of my life on 'Potter'. It was very strange.''

Rupert starred in the money-spinning film franchise alongside Daniel Radcliffe and Emma Watson.

And he's admitted that they all experienced very different childhoods compared to most people.

He said: ''We were always with adults, absorbing their sense of humour, their references.''

In fact, Ruper has confessed to feeling detached from some of his classmates because of his experiences on the 'Potter' films.

He shared: ''I always remember, the few times I did go back to school to do exams, I felt a real detachment from my peers.

''We had very little in common, which is quite isolating in a way. Which is why I think it felt like such a strong family unit on set. When you're in it, you don't really think about that.''
