Imagine walking into a tattoo parlor with Liam Hemsworth and his family. It was a reality for Jennifer Lawrence [1], who chatted about her "H2O" mark at Comic-Con last week. "I was with Liam's family, and everybody was getting tattoos. And I was like, 'Well, I'm always going to need to be hydrated.'" Then the actress gave a closeup of her tattoo, which was visible during her time on the red carpet.

When Jen wasn't giving fun interviews, the actress freaked out when meeting Bill Murray [3] and later let Hugh Jackman sit on her lap [4]. Take a peek at her new ink in the video above, then check out the ultimate celebrity tattoo gallery [5].
