Rihanna prepares for performance by posing topless in yellow underpants

She does, however, protect what's left of her modesty ...

Rihanna doesn't feel the need to live an undocumented life. Every thought, action and impulse becomes a shared experience with her fans, including this coif-molding moment with her hairstylist before a concert on Monday night in Atlanta. The chanteuse, who's back in the pink after missing a few dates on her Diamonds world tour due to an apparent throat infection, posted this titillating pic on Instagram. "Show time!" she enthused, adding, "#ATL is all miiiiiinnneee!!!! I want you on your WORST behavior!!! Tonight is all about you!!!"
