Lady Gaga looked typically stylish as she posed with co-star Joaquin Phoenix at Joker: Folie à Deux photocall during Venice Film Festival on Thursday. 

The singer, 38, who stars as Harley Quinn in the upcoming thriller, donned a black skin-tight top and wide leg trousers, while accessorising with shades.

Gaga, who opened up about fiancé Michael Polansky's proposal on Thursday, posed with her co-star Joaquin, 49, who has reprised his role as Arthur Fleck AKA Joker in the new film.

Gaga and Joaquin are currently promoting their new film Joker: Folie à Deux at Venice Film Festival.

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.

Elsewhere, Gaga opened up about her love for fiancé Michael Polansky in a candid interview with Vogue.

The couple's engagement was revealed to the world in July this year, with Michael actually getting down on one knee back in April after a day of rock climbing.

Gaga was first romantically linked the tech entrepreneur linked around New Year's Eve 2019 and later went Instagram official in early 2020, with the couple remaining relatively private about their relationship.

Wedding plans for the couple are underway and their legal plan is being negotiated. 

And Gaga - real name Stefani Germanotta - told how it was actually her mother Cynthia who met him first and thought he was perfect for her daughter, telling the singer: 'I think I just met your husband!'

Gaga was at first apprehensive after insisting to her mother that she was 'not ready' to meet her husband, but then noted to the publication that she was later excited at the prospect of bumping into him at Facebook founding president Sean Parker's 40th birthday party.

After she did indeed run into Michael, the star recalled how they spoke for 'three hours' and had the most 'amazing conversation', with their meeting later leading to weeks worth of phone calls ahead of them finally going on a first date together where they 'fell in love'.

The pair's relationship blossomed as Covid hit and they hunkered down in her Malibu abode for over a year, with Gaga describing the break from her busy schedule and cohabitation with the businessman as 'really kind of special'

Polansky is a 2006 graduate of Harvard University and runs Napster founder Sean Parker's Parker Group.

Throughout their years dating, Gaga and Polansky have attended the Super Bowl , the BAFTAs, and the Critics Choice Awards together.

Lady Gaga and Michael reportedly decided to go their separate ways in early 2023 due to the singer-songwriter wanting marriage and children and the tech executive not being ready to take those steps.

The pair reportedly had an amicable dissolution to their coupling, and remained friends.

Then, in August 2023 they were spotted together for the first time in more than a year.

The singer has always been open about her desire to have a big family and in 2013, she told Sirius XM radio she wants 'at least three kids'.

She said: 'I wanna have tons of kids. I think at least three. I really want to have a family. I really want to have a family, I really want to nurture my children.

'Having my own kids will be like having three little monsters with me all the time. They probably won't be fans, they will probably hate my music - who knows.

'I want to have a family, I want a family life. I grew up with a very strong family and I can't imagine not having a normal nuclear family.'

She also expressed the desire to start a family with Michael, 46, back in 2021 after their relationship started heating up.

'She has been telling her friends that she wants to get through a few projects and then focus on settling down,' a source told Entertainment Tonight at the time.

'Gaga wants to have children one day and sees a future with Michael.'

The entertainer had two previous engagements that were called off.

She ended her engagement to Christian Carino in early 2019, and after becoming engaged to actor Taylor Kinney in 2015 they broke up in 2016.
