Even though she and John Mayer broke up, looks like some of his rocker style rubbed off on Jess! Earlier this week, she was spotted in NYC wearing this Rolling Stones tee. Other stars like Brittany Snow, Avril Lavigne, Fergie, and Mischa are rockin' out, too!

Whatever your music preference, though, flaunt your fave rocker tee with pride!

You Say!
