Britney Spears is apparently the fastest person alive.
In a now deleted post on Instagram, Spears claimed to have run the 100-meter dash in 5.97 seconds. For context, the world records for the 100-meter are held by Florence Griffith Joyner, who ran it in 10.49 seconds, and Usain Bolt, who ran it in 9.58.
Spears would later claim that she was only making a joke about breaking the world record from 100-meters, writing on Instagram, "PS …. obviously I was joking about running the 100 meter dash in 5.97 seconds …. the world record is held by Usain Bolt which is 9.58 seconds …. but you better believe I’m coming for the world record -- !!!! #joking"
