BRITNEY Spears has terrified fans by dancing with knives in her latest Instagram video.
The pop icon shared a bizarre video with her 42.1 million followers on Monday night in which she held a huge blade in each hand.
The 41-year-old — who regularly dances in a bikini on the site — wore white bikini bottoms and a polka dot top as she used the kitchen knives to slice through the air.
Three dogs watched Britney work up a sweat while spinning around but ran away when she kicked and twirled in their direction.
The Toxic singer shared the clip without a soundtrack and told her fans she was looking forward to Halloween.
She wrote in the video: “I started playing in the kitchen with knives today !!! Don’t worry they are NOT real knives !!! Halloween is soon!!!”
Britney has disabled comments on Instagram but the video has been circulating on X, formerly Twitter.
One fan reacted with scared face emojis: “Those were 100% real knives in Britney’s latest Instagram video.”
Another said Britney had been inspired by Shakira who danced at the VMAS with knives and said: “I love that my girl Brit was inspired by Shakira but Shakira used prop knives that were realistic but also safe to dance with.
“I just hope Britney gets it out of her system and put the knives down and order prop knives to dance with in the future.”

An insider told The Sun that the pair were locked in a series of explosive rows in the dying days of their marriage.
Sam is also said to have grown frustrated by his wife stripping off on the internet, posting scantily clad and fully naked snaps.

She hinted at Sam lying to her in a cryptic Instagram post recently, writing: “How many times have you guys been lied to or tricked by someone you loved ??? Psss on repeat because well … I MEAN IT !!!”
