Bruce Willis, 67, has lunch with friends amid his battle with aphasia

Bruce Willis stepped out with friends in Los Angeles on Monday amid his battle with brain disease aphasia.

The 67-year-old retired actor, whose daughter Rumer is expecting their first child, soaked up some sun as he headed out for a bite to eat and a freshly squeezed green drink.

The Hollywood icon retired from acting earlier this year as he began his battle with the illness that was causing his language skills to deteriorate.

Last month, Bruce found out he’s going to be a grandfather when his 34-year-old daughter Rumer announced she was pregnant with boyfriend Richard Thomas.

In November, Willis was reunited on screen with his former co-star John Travolta in the action-packed film Paradise City.

The film is one of the last Willis completed before his family announced in March that he was retiring from acting after being diagnosed with aphasia.

The film also marks the first major collaboration between Willis and Travolta since they starred in Quentin Tarantino’s 1994 classic crime drama Pulp Fiction.

Willis plays an aging bounty hunter in Hawaii who takes on one of his most dangerous missions yet.

After being shot and left for dead, his son Ryan (Blake Jenner) teams with his father’s former partner (Stephen Dorff) to hunt down his killers while dealing with a sadistic crime boss (Travolta).
