Jennifer Lawrence has ''the most un-rebellious tattoo'' ever on her hand.

The 'Hunger Games' beauty had the chemical symbol for water, H20, etched on her hand but insists it was a completely random choice.

She said: ''It's not like a real tattoo. I was like, 'I'm always going to need to be hydrated. So I guess I should just get 'H2O' on my hand.

''It's literally the most un-rebellious tattoo that anyone could ever get.''

The 24-year-old star also noted that the tattoo was inked incorrectly and should feature a subscript, ''low'' 2 rather than a superscript, ''high'' 2.

She added to HitFix: ''I should have Googled it before I got it tattooed on my body forever.''

And Jennifer has no need to worry about the incorrect inking affecting her job as she insists the industry ''doesn't care'' what people look like when they become big enough stars.

Speaking about body image, she said: ''I had a conversation with somebody about the struggles with weight in the industry - I know that's something I talk non-stop about. And they were saying, 'All of the main movie stars aren't very underweight.' I said, 'Yeah, because once you get to a certain place, people will hire you. They just want you to be in the movie, so they don't care.'

''It's more about the struggle for actors and actresses who have not made it to a certain place, and there's a lot of pressure.''
