The 35-year-old pop star shared a collage of four pictures showing herself making funny faces while holding her thumb up and index finger out.
'Don't underestimate the power of Charlie's [angel emoji],' Britney wrote in the caption for her nearly 50 million followers on Twitter.
The Toxic singer was referencing the pose first made famous in the 1970s TV show Charlie's Angels starring Farrah Fawcett, Jaclyn Smith and Kate Jackson.
Fans of the singer were no doubt left shocked, confused and upset earlier on Monday, when the global account for Sony Music tweeted she had passed away.
However a representative for Sony confirmed the tweets were part of a hack, saying: 'The twitter was hacked and the tweets are now deleted. Britney Spears is alive and well.'
The first initial tweet simply read: 'RIP @britneyspears #RIP 1981-2016.'
