Charlize Theron would never auction herself for a dinner date for charity again.

The 'Prometheus' actress previously offered herself up as part of an auction, and she admits she was so nervous about going out with a ''strange man'' she had her friends sit in the same restaurant as her.

She told talk show host Conan O'Brien: ''Do not do it. It's like the worst idea ever. It's one of those things. I was like, 'Yeah I am a dumb blonde'.

''They trick you with the, 'People are suffering', thing. You fall for it and before you know it you're at a restaurant with a stranger.

''I went to dinner with a strange man. I made two of my girlfriends sit in the restaurant with me. Strange people can be creeps too! It was a scary thing. And he was weird.''

Now, the Oscar-winning star claims she will just give the cash directly to the needy group.

She said: ''Look, I'd rather just five the money to charity.''

Dates with strangers are not the only thing that scares Charlize; she also claims her part in the 'Mad Max' remake is also nerve-wracking for her.

She added: ''I feel like the original 'Mad Max' created such a vivid world, that to go back and re-imagine it and kind of replay in that sandbox sounds like fun to me.

''George really created a female character that I've never read anything like this. I mean, I'm scared sh**less!

''I'm very excited about it; I'm f*****g dying! It's been three years; it's time to skin this cat already!''
