Jennifer Lawrence opens up about her scientifically incorrect 'H2O' tattoo

You may never have noticed it due to its colour and size, but Jennifer Lawrence has the chemical symbol for water (H2O) tattooed on her right hand, which she has recently described as "a watered-down rebellion".

"It's not like a real tattoo," she stated, in an interview with Hit Fix. "I was like, 'I'm always going to need to be hydrated. So I guess I should just get 'H20' on my hand."

The 24 year old went on to admit that she only got the symbol done because she was hanging out with her Hunger Games co-star Liam Hemsworth (who plays Gale in the hugely popular saga), when he and his whole family decided to get some permanent body art.

Feeling propelled to keep up with the Hemsworths, Lawrence opted for something subtle (and random), even making sure to choose ink that was particularly lowkey, the Silver Linings Playbook actress disclosed.

"It's the colour of a scar, all natural so it's literally the most un-rebellious tattoo that anybody could ever get."

However, one thing that she didn't carefully consider when it came to getting the tattoo was making sure she got the scientifically accurate representation of the symbol. "By the way, I know that the two is high and [in] H2O the two is supposed to be low," she affably explained, while staring into the camera. "I should've Googled it before I got it tattooed on my body forever."

Despite people only just noticing her permanent hand decoration, the American Hustle actress appears to have had it for quite some time, with a number of publications claiming that it was first seen on her hand in July 2014.

Lawrence reportedly attended a Coldplay concert with Hemsworth and fellow co-star Josh Hutcherson on 1 July of that year and her hand was reportedly bare. However, stepping out at a fashion show in Paris on 8 July – the tattoo was there.

The Oscar winner was at this year's San Diego Comic-Con to promote two movies that she will be starring in within the next year, The Hunger Games: Mockingjay – Part 2 and X-Men: Apocalypse. The former film, will see her reprise her role as Katniss Everdeen for the last time, is scheduled for UK release on 20 November, and she will portray Mystique in the world of mutants on the big screen once again come 2016.
