Cameron Diaz was back at work as she was seen on the set of her new film Outcome for the first time.

The actress, 51, was seen shooting the dark comedy with Keanu Reeves and Matt Bomer in Los Angeles on Wednesday.

She wore a brown corset style dress and leopard print leggings with her feet slipped into Birkenstocks.

It comes just over a month after Cameron announced she and her husband Benji Madden, 45, had welcomed their second child together, a son named Cardinal.

Outcomes follows Reef (Reeves), described by Deadline as ‘a damaged Hollywood star who must dive into the dark depths of his past to confront his demons and make amends after he is extorted with a mysterious video clip.’

It’s unknown what role Cameron is playing in the film.

The project also stars Jonah Hill, who is set to direct the movie. 

Cameron appeared in high spirits as she prepared to throw herself into character, a huge smile on her face as she emerged from a building with the production crew gathered around. 

Her long, blonde locks were perfectly styled into a sleek ‘do with a stylish center part. At times she rocked a pair of smart spectacles.

Keanu donned a white T-shirt, jeans, and suede footwear for his day on set.

The Matrix alum strode across the set alongside Matt, who sported a quirky get-up consisting of a floral print button down and yellow jeans. 

The sighting comes after Cameron un-retired from acting to star opposite Jamie Foxx in the upcoming film Back In Action. 

It also comes after Cameron announced the arrival of her second child with husband Benji.

She announced his arrival on Instagram back in March, gushing her newborn is ‘really cute’ but adding she wouldn’t be posting photos for his ‘safety and privacy.’

Cameron did not reveal Cardinal’s date of birth or how he was conceived.

The couple, who wed back in 2015, also share four-year-old daughter Raddix.

‘We are blessed and excited to announce the birth of our Son, Cardinal Madden,’ wrote Cameron, who included a piece of artwork that read: ‘A little bird whispered to me.’

She continued: ‘He is awesome and We are all so happy he is here! For the kids safety and privacy we won’t be posting any pictures- but he’s a really cute

‘We are feeling so blessed and grateful Sending much love from our fam to yours Best wishes and Good Afternoon!!’ Cameron concluded.

The announcement was accompanied by a drawing with the words: ‘A little bird whispered to me,’ written on the front.
