Britney Spears has clarified that she isn’t faster than Usain Bolt, following a confusing boast about her personal best speed.

The pop icon claimed, in a since-deleted post on her Instagram, that she usually manages to run 100 metres in “six or seven seconds”. Even more impressively, she also claimed she’d just managed to achieve the feat in under five.

Observers were quick to point out, however, that Bolt currently holds the world record for fastest person to run 100 metres – and in 9.58 seconds, which is significantly longer than Spears (allegedly) on an average day.

She has now clarified that her claim was merely a joke.

In a caption for a video showing her posing in a yellow dress, Spears wrote: “Obviously I was joking about running the 100 metre dash in 5.97 seconds.”

She added: “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 #workbitch”

“We will feed each other, re-destribute [sic] wealth, strike,” read an image posted to Spears’ Instagram. “We will understand our own importance from the places we must stay. Communion moves beyond walls. We can still be together.”
