Britney Spears has triggered some late 90s nostalgia with her latest video.

The pop princess posted a clip on Instagram of herself dancing to Meghan Trainor and it is vintage Britney, complete with those snappy steps, swivelling hips and hair tossing.

Wearing just a skimpy pair of pink shorts and a tiny top (and, oddly, what appeared to be a choker), Brit also showcases her toned legs and super flat tummy.

She wrote: “It’s been a while since I cut loose.”

A piece of gym equipment is in the background, suggesting that the star was throwing shapes as part of a work-out.

Britters is clearly all about the dance of late – earlier this month she shared videos online of herself teaching some youngsters one of her routines.
