Rihanna reveals mystery scar on her chin

Rihanna surprised fans at V Festival over the weekend when she revealed an as-before-unseen scar on her chin.The 23-year-old singer lifted up her head and displayed the two tiny scars as she performed on stage at the music event at Hylands Park in Chelmsford, Essex.
It is not known how Rihanna got the scar, but the singer didn't have it when she performed on The X Factor last October.
The scar could possibly be from a plastic surgery procedure, such as chin augmentation or reduction or a chin lift.It has previously been reported that she also has a permanent scar on her lip from where her ex-boyfriend Chris Brown punched her in 2009
