Brit & J Go For A Couple's Makeover!

Is that a wig on Brit's head or did she just go crazy on the extensions and Garnier? And what's up with Jason's lighter 'do -- he washed that gray right outta his hair!

But really, y'all -- it looks like Britney's just having fun and thank god she found a guy to have fun with! Don't these two look totally relaxed now that they've gone public with their relationship?
