The 11-year-old daughter of Will Smith and Jada Pinkett Smith had posted a photo on her official Instagram page, where she appeared to have a tongue stud.
Meanwhile, her friend also had a silver chin stud in the photo, revealed yesterday (June 24).
She has since become a trending topic on Twitter worldwide following the photo, with many stating their concern due to her young age.
However, she later insisted that the piercing isn't real, writing: "It's fake... Sorry".
The 'Whip My Hair' singer is currently working with her father and Jay-Z on an upcoming remake of the musical Annie.
Her debut album Knees and Elbows is expected to be released later in 2012.
