Beloved pop star looks unrecognisable in a cropped red wig as she films her new music video at The Louvre - can YOU guess who it is?

One of the planet's biggest pop stars looked unrecognisable as she filmed the music video for her upcoming single at the Louvre Museum in Paris. 

Lady Gaga, 38, was spotted in a cropped red wig on a balcony in the famous French museum on Friday night and Saturday morning.

The Poker Face songstress put in a long shift for her project and was filming scenes from 10pm until around 2.30am.

The star was seen inside the gallery and out on the terrace, with views out over the glass pyramids and the Olympic balloon. 

In the photos Lady Gaga, whose real name is Stefani Germanotta, was seen craning her neck over the balcony edge and looking around, lit up by spotlights in the dark. 

She sported a black lacy dress with a large white lace collar in a v-neck.  

The Bad Romance singer wasted no time getting back to her new music and jetted off to the French capital after attending the Joker: Folie à Deux premiere at the Venice Film Festival on Wednesday where she put on a loved-up display with her fiancé Michael Polansky.

The news of her new music video comes as she announced the release of her new track due in October and teased her new album.

Lady Gaga has been hinting at new music and a new album for a while and recently released a duet with Bruno Mars called Die With a Smile.

The singer and actress and the Silk Sonic performer, also 38, shared their surprise collaboration last month after announcing it earlier that week. 

Lady Gaga's musical news comes hot off the back of her starring role in the latest Joker film.

In celebration of the release of the film, also starring Joaquin Phoenix, Lady Gaga stunned on the red carpet at the Italian film festival. 

The singer, who stars as Harley Quinn in the upcoming thriller, wore a dramatic black gown and headdress as she joined her co-star and his sister Rain at the screening.

She looked stunning in the plunging dress which featured a velvet corset-style top which then flowed into a dramatic puffy skirt.

The look was completed with an intricate lace headdress, huge diamond earrings and a bold red lip - while she wore her bright blonde tresses in a neat bun.

The singer and actress gazed adoringly at Michael as she flashed her enormous 8 carat engagement ring on the star-studded red carpet.

Michael, a tech entrepreneur, looked smart in a black suit, crisp white shirt and bow tie.

Folie à Deux will see Joaquin, 49, reprise his role as Arthur Fleck AKA Joker and he arrived to the premiere with his glamorous sister Rain.

She looked great in a brown velvet gown and donned stylish shades as she posed with her brother.

It is the much-anticipated follow-up to 2019's Academy Award-winning Joker, which earned more than $1 billion at the global box office and remains the highest-grossing R-rated film of all time.

Set for release on October 4, the second instalment finds Arthur Fleck institutionalised at Arkham awaiting trial for his crimes as Joker.

'While struggling with his dual identity, Arthur not only stumbles upon true love, but also finds the music that's always been inside him,' a press release shared.

Lady Gaga has been supported by her fiancé Michael in the lead up to the thriller's premiere.

The couple was first romantically linked around New Year's Eve 2019 and later went Instagram official in early 2020.
