Anna Kendrick won't tweet drunk.

The 'Into the Woods' actress is known for speaking her mind on the social networking website but always makes sure she takes precautions not to say anything she'll regret later.

She said: ''I drunk draft and double check them in the morning.

''Although I have done a handful of drunk tweets and so far people have not been able to tell the difference although I'm not quite sure if that's a good thing or a bad thing that my sober tweets could be drunk tweets.''

The 29-year-old beauty was surprised to discover her more ''innocuous'' postings tend to attract more questioning about her intentions.

She said: ''It's funny because I feel like when I try to say something really innocuous, those are the ones where people are like, 'What do you mean by that?'

''Sometimes, I just say something kind of gross, kind of honest, maybe a little too brutal. Those are the ones people respond to more.

''It's when you try to say something that's a little too squeaky clean that people are like, 'What's that? What are you doing? What's going on?'''

And one of the downsides the 'Up in the Air' star has found to social media is the number of former classmates who have used it to get in touch.

She told E! News: ''Every now and then, I'll get a blast from the past.

''I don't think we were close but sure, next time you're in L.A. I guess [we can hang].''
