Cameron Diaz, 53, looks worlds away from her usual glamorous self as she films dramatic scene with co-star Stephen Merchant for upcoming rom-com in NYC

Cameron Diaz looked worlds away from her usual glamorous self as she filmed a dramatic scene with her co-star Stephen Merchant in New York City on Saturday.

The duo are set to star as unlikely lovers in the upcoming film The Sham, after Cameron previously gushed about her British co-star upon landing the role. 

While shooting scenes in the city, the American actress, 53, donned a quirky ensemble as she appeared to chase Stephen, 51, down a street. 

Emerging from an apartment on set, Cameron wore a bulldog graphic print T-shirt styled as a dress, teamed with vibrant, tight-fitting leggings. 

She layered a fluffy beige cardigan over her shoulders and completed the look with green Ugg boots. 

Accessorising her outfit, the star sported a white and black polka dot bandana headband and hoop earrings, while putting on an emotional display for the scene. 

Meanwhile, Stephen cut a smart figure in a burgundy blazer paired with a navy waistcoat and grey trousers as he strode ahead of Cameron along the sidewalk. 

Later in the day, Cameron switched into a cream knit hoodie and grey jeans as she relaxed on a set of stairs with her lines in hand. 

She later changed once again, opting for a burgundy top and the same beige cardigan while filming a scene in which she took out the trash from her apartment. 

The star appeared in great spirits as she paused to chat with members of the production team. 

For her final look of the day, Cameron cut a stylish figure in a red blazer paired with a white graphic T-shirt and light-blue denim jeans as she left what appeared to be a comedy club. 

According to Deadline, The Sham sees Stephen play a British hotel worker who is employed at an upscale New York hotel, and desperately needs a wife to maintain public appearances.

He then joins forces with a struggling comedian, played by Cameron, who needs cash to fund her health insurance.

While the pair's fake marriage begins as a business transaction, it soon turns into an unexpected romance. 

Last week, Cameron shared she would be starring alongside Stephen, famed for his work including The Office in the UK, while appearing on The Tonight Show Starring Jimmy Fallon.

Praising her co-star, she said: 'I'm doing a movie with Stephen Merchant, so great, gosh he is the best. I'm doing a film here with him. I don't know the name of it yet.'

Stephen echoed the sentiment by sharing the clip on his TikTok, writing: 'Thanks so much for the love @Jimmy Fallon and @Cameron Diaz. Having a great time making this movie in glorious NYC, can’t wait to share it.'

Cameron took a break from Hollywood in 2014 after the film Annie, but returned just last year to star alongside Jamie Foxx in Back in Action.

One of her next movies is Shrek 5, set for release in 2027.

The film will see Mike Myers, Eddie Murphy and Cameron all reprising their roles as Shrek, Donkey and Fiona, respectively, while Zendaya joins the cast as Shrek and Fiona's daughter, Felicia.

Cameron will also star in Reenactment with Benicio del Toro.

While plot details for Reenactment are being kept under wraps, reports claim the film will soon enter production in LA. 

She is also set to star in the Netflix movie Bad Day, having signed on to feature in the streaming giant's project from director Jake Szymanski, who helmed the acclaimed comedy series Jury Duty.

The movie centres on a single mother who is fighting to keep one small promise to her daughter on the worst day of her life.

The picture has been described as a comedic version of Joel Schumacher's 1993 film Falling Down, in which Michael Douglas plays a man who reaches his breaking point while trying to reach his daughter's birthday party.
