We're thinking this is some sort of a strategic move to work around her wardrobe, but who knows!

Rihanna tweeted a photo of herself and her hairdresser getting ready last night before her concert in Atlanta, and earlier in the day she tweeted, "I want you on your worst behavior!" She certainly knows how to get the party started!

And speaking of partying, we're amazed that she's recovered so quickly after reportedly cancelling a handful of concerts due to laryngitis.

"This is the hardest thing for me to deal with! I feel like we've been waiting on this day forever, and I'm hurt that I let you down," she told her fans in Baltimore and Boston after cancelling three shows, including a date last week in Houston, Texas. "I hate disappointing people that never ever let me down!! I'm so embarrassed about this! Thank you for your prayers and well wishes!"
