Rihanna - Tweets Topless Pic From Back Stage

Rihanna no stranger to showing off her goods to the whole world, and Rihanna's most recent posting on her Instagram account showed her completely topless.

While preparing for her concert in Atlanta, Georgia last night (April 22), the "We Found Love" songstress shared a photo of herself covering up with a towel while her hairstylist finished the final touches. The photo caption read "Show Time!"

Just a few hours before the photo was displayed, Rihanna tweeted to her Atlanta fans, "I want you on your worst behavior! Tonight is all about you!"

Since her Diamonds world tour began last month, Rihanna canceled three concerts due to illness with the most recent being her April 15 performance in Houston, Texas.

RiRi apologized to the fans in Baltimore and Boston via Twitter, saying, "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!"

To make up the cancellation of the March 12 show in Baltimore, Rihanna will perform at the 1st Mariner Arena on Wednesday (April 24th).
