Cooper, who is directing and starring in the drama, wore a tan button-up shirt and dark denim jeans. His body double rocked a similar look and even nailed Cooper's scruffy beard.
Earlier in the week, Cooper and his co-star, Lady Gaga, were spotted filming a steamy kissing scene near Palm Springs, California.
The film marks Gaga's first lead role in a feature film, and she is being billed as Stefani Germanotta, her real name. The 31-year-old singer will play Ally, an aspiring, up-and-coming singer. Cooper will play Jackson Maine, an alcoholic country music star on the decline who tries to help Ally become famous.
