Rihanna is clearly comfortable in her own skin. Before she performed in Atlanta on Apr. 22, the "Nobody's Business" singer shared a racy Instagram picture with fans. The image features the topless pop star holding a towel over her breasts as her hairstylist tends to her curls. "Show time!" Rihanna wrote in the caption.

Since kicking off her Diamonds World Tour in Buffalo, New York, March 8, Rihanna has canceled three concerts to due illness. "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 contracting laryngitis. "I hate disappointing people that never ever let me down!! I'm so embarrassed about this! Thank you for your prayers and well wishes!"

Rihanna most recently canceled her Apr. 15 concert in Houston, Texas, as "a result of illness." She has since resumed her touring schedule and will next perform at Baltimore's 1st Mariner Arena to make up for her canceled March 12 show.
