Zac Efron says he will never be able to date anyone.

The 'Neighbors 2: Sorority Rising' star doesn't think he will ever go on a ''dictionary definition'' date with a girl as it would take a very long time to ''dispel whatever people think'' about him.

He said: ''Dating is something I'll never be able to do. As in the dictionary definition of dating, because one way or another I've impacted that person's life and they'll soon see it. A date has to be very long to dispel whatever people think about me.''

However, that's not to say Zac hasn't tried the more modern methods of dating, including signing up to the dating app Tinder, but claims he was rejected because nobody believed it was actually him.

He said: ''Amazingly, when I signed up for Tinder, nobody swiped me! They thought it was fake. That never happened. Aha-ha.''

And the 28-year-old actor also admitted he ''lost his mind'' because of the internet as he would focus on the negative things people said rather than the positives.

He added to The Times newspaper: ''I lost my mind because of the internet. I'd read 30 positive things and one bad thing, then I'd focus on that bad thing. It drove me crazy.''

Meanwhile, Zac previously revealed he used to Google himself every morning.

He said: ''What I found is structure. That led me to a balance of opposites. You get out of life what you put in.

''There was a moment when my morning routine was, like, get up and Google yourself. But that stopped, dramatically and instantly, probably three years ago. I saw that viewing yourself through other people's pictures is not living your own life.

''I wasn't really being myself. A lot of my hobbies had gone out the window. I couldn't skateboard or surf for fear of being followed. Crossing the line of fear is what leads to greatness.''
