Bradley Cooper wears a t-shirt for Sean Penn’s charity CORE, which helps communities in Haiti while the actor is seen in New York City

Bradley Cooper wore a Community Organized Relief Effort t-shirt while taking a leisurely stroll through New York City on Monday.

CORE was co-founded by Bradley’s acting colleague – they collaborated on 2021’s Licorice Pizza – and friend Sean Penn and Penn’s business partner Ann Lee.

The charity was originally set up in the aftermath of the catastrophic earthquake in Haiti in 2010.

The Guardians of the Galaxy 3 star paired the CORE t-shirt with jeans and Nike sneakers.

And he kept it simple with black sunglasses.

Aside from his vocal work as Rocket Raccoon in the Guardians of the Galaxy trilogy (and associated MCU movies), the 48-year-old actor is also best known for his Academy Award-nominated role in A Star Is Born.

In 1999, the then unknown Hollywood star-to-be made his on-screen acting debut in the HBO series Sex and the City.

While his first major movie role was in 2001’s Wet Hot American Summer, Bradley’s status as one of Hollywood’s biggest names was sealed with his role in 2009’s R-rated hit The Hangover.

He would go on to star in a series of big movies, such as Silver Linings Playbook and American Sniper.

The Pennsylvania-born superstar would also reprise his star-making Hangover role in the sequels.

Off screen, Bradley was briefly married to Blue Bloods star Jennifer Esposito.

After the couple divorced in 2007, Bradley was linked to Russian model Irina Shayk in 2015.

Before the couple split in 2019, they had a daughter together, Lea De Seine.

Although Bradley has his hands busy with his acting career and co-parenting Lea, he still makes time to support charitable organizations like CORE.

While CORE was initially founded in the aftermath of Haiti’s devastating 2010 earthquake, the nonprofit now aims to “provide immediate relief and recovery to underserved communities around the world,” according to CORE website.

The Marvel star also founded his own charity, the One Family Foundation, a partner of the Social Impact Fund.

Bradley’s foundation aims to relieve the stress of cancer patients and their families.

Over the years, the Oscar-nominated actor has also lent his support to a number of other charities, including the Cancer Research Institute, Stand Up to Cancer, and the Melanoma Research Alliance, among others.
