Britney Spears dances in a bra and cheeky fringe shorts as she hints at new project with director Jon M. Chu that's NOT her biopic

Britney Spears showed off her moves in a bra and fringe shorts in her latest social media update.

On Friday, the 42-year-old pop star took to Instagram to share a video of herself dancing in a white, boho-chic lingerie set and tall espadrille wedges.

In the clip, she was seen moving her hips and lip-syncing to Clean Bandit's 2016 song Rockabye featuring Sean Paul and Anne-Marie.

Halfway through the video, she changed into a colorful, watercolor-style push-up bra.

The Gimme More hitmaker — whose former assistant recently floated Emma Roberts as the potential lead in the Princess of Pop's forthcoming biopic — added a pink heart emoji to her post and wrote in her caption: 'To the one I love!!!'

The singer ended off the reel with a clip of herself, wearing the white two-piece set again, posing for photos after turning off the music. 

In the video, she was seen adjusting her sexy, skimpy ensemble and dancing carefully with one of the straps on her shoes unfastened. 

Her blonde hair was styled in her voluminous and tousled look and pulled back into a half-up and half-down 'do. 

She accessorized with a black choker and a dainty pendant necklace to keep the focus on her revealing outfit and bold moves. 

At one point during her clip, she cupped her chest with her hands and was seemingly readjusting her top while dancing.

Then, she lipsynced passionately to the lyrics in the song's chorus: 'No one's ever gonna hurt you, love. I'm gonna give you all of my love. Nobody matters like you.'

Her caption seemingly referred to these lyrics too as she did not include any other snippets of her lip-syncing or singing to the song. 

On the same day, Spears also shared a post in which she reshared an artist's drawing and a message, hinting about a new project she's working with director Jon M. Chu that's not her biopic.

'The project I might be doing isn't a biopic story,' she penned over a plain, baby pink background.

'It's a fictional musical where I play an extremely intelligent character,' she wrote alongside a winking face emoji and three exclamation points. 

She added: 'It's flattering to be in such good company like Jon Chu!!!' 

Spears' announcement of an upcoming project comes a month after it was announced that Chu — who is known for directing Crazy Rich Asians as well as the Ariana Grande and Cynthia Erivo-led film adaptation of Wicked — would be working alongside producer Marc Platt to develop the feature film based on Spears' bestselling memoir, The Woman in Me. 

At the beginning of August, Spears shared the exciting news of a 'secret project' she had started working on alongside Platt, who she said 'always made my favorite movies.' 

The biopic will be based on Spears' bombshell tell-all, which she released last October. 

Her memoir chronicled her journey from childhood to pop superstardom including her Mickey Mouse Club days, her highly publicized relationship with Justin Timberlake and her infamous conservatorship and family. 

Since the scrutinized case ended and she was formally freed from her conservatorship in November 2021, Spears has chosen to remain largely out of the spotlight with the exception of the dancing videos she frequently posts on Instagram. 

Earlier this year, she declared that she 'never will' return to making music and performing again.

She said she will only work in within the music industry as a ghostwriter for other artists. 

It is unknown when production on the biopic is slated to begin, and as such, a release date has not yet been revealed.
