Beyoncé's alter-ego. Its a level of fierce too.
Beyoncé created this character for fun & wanted to try something new back in 2008-2013.
Sasha Fierce made her first appearance in the iconic music video "Single Ladies".
Apparently,
Sasha's last appearance was at the 2013 SuperBowl.
Just like how Nicki Minaj has her own alter-egos she acts out. (Roman,
Lewinsky, Martha, Barbie etc)
