Jennifer Lawrence revealed her new tattoo while at the Comic-con annual convention last Thursday to promote her movie, The Hunger Games: Mockingjay – Part 2.

In a video interview with HitFix, the 24-year-old actress showed an obscure scar-colored tattoo on her right hand that says H2O, which she humorously described as a “watered down rebellion” because of its light shade.

However, Lawrence acknowledged that there was an error on her permanent marking, as her tattoo featured a 2 that is inked on top while the chemical formula for water should have a 2 on the bottom.

Admitting her mistake, the Hunger Games star joked that she should have researched it on Google before having it marked permanently.

Apparently, the Silver Linings Playbook actress was on an outing with Hunger Games co-star Liam Hemsworth and his family when she got the tattoo, seeing that everybody else was getting inked.

Lawrence explained that she thought of getting an H2O tattoo since she knows she will always need to drink water — good reason.

A closer look at the actress’ pictures during a fashion show in Paris on July 8, 2014 revealed that the three-symbol tattoo was already on her right hand, according to Mail Online.

Lawrence must have had the tattoo after attending the Coldplay concert on July 1, 2014 with co-stars Hemsworth and Josh Hutcherson.

Meanwhile, the actress was also happy to meet Ghostbusters star Bill Murray at the Comic-con convention and posed for several photos with him.

Lawrence admitted that she was a huge fan of Murray, and that she sent emails to co-star Woody Harrelson about stuff that she would say to the Ghostbusters actor.
