Samantha Ronson is ready to scratch the heart tattoo she got in 2008 with Lindsay Lohan. Sources said Ronson headed to a tattoo station at Chicago’s Lollapalooza where she helped design a skull and crossbones for guitarist Jimmy Messer from her band, the Undertakers. While watching the artist work on Jimmy at the Miami Express Yourself Oasis, a spy said, “Samantha brainstormed ideas for her next tattoo, which will be something on her left hand to cover up the small heart she got in 2008 to match Lindsay’s tattoo.” A more sober Lohan was also there for the festival, but the two didn’t cross paths.
