Britney Spears has shared the entire contents of a “cursed” videotape that features in horror movie, The Ring.

The 2002 supernatural horror stars Naomi Watts as a journalist named Rachel Keller, who discovers a creepy videotape that kills the viewer seven days after watching it.

On the recording are strange and scary images which come to life as the movie progresses, until dead girl Samara crawls out of the screen with long and bedraggled wet hair.

Spears, 42, shared the whole contents of the scary tape as a reel to her Instagram page, which boasts 42 million followers, on Wednesday (5 June).

“Does anybody remember this movie where they hold this little girl captive too long and she finally comes out of the TV walking on her hands and knees and destroyed half the nation?” she wrote in a caption alongside the eerie footage.

“Y’all stay cozy! You guys have nothing to worry about at all! Love y’all!”

Fans were simultaneously terrified and bemused at the post as they shared their reactions to the doomed clip.

“Imagine if we all die in seven days because Britney Spears posted The Ring video on her Instagram,” wrote one person.

“Britney Spears just lobbed The Ring video onto the timeline and I’m obsessed. Imagine she just casually cursed 42.2 million people with one post? Mother Mayhem,” posted another.

Some found the action “so funny” and a “severe vibe” while sarcastic commentators added, “Waking up to Britney Spears posting the full cursed video from The Ring… it’s gonna be a great day”.
