The 67-year-old was caught on video by his wife Emma Heming Willis, 44, in an Instagram post showing the actor sitting down with closed eyes and playing the harmonica as his friend sang along and played an acoustic guitar.
This comes after over four months since the Willis family revealed that the Pulp Fiction actor had been diagnosed with aphasia, which impacts speech, and stepped away from his acting career.
The family, including the actor’s ex-wife actress Demi Moore, had put out joint statements saying: “To Bruce’s amazing supporters, as a family we wanted to share that our beloved Bruce has been experiencing some health issues and has recently been diagnosed with aphasia, which is impacting his cognitive abilities.

“As a result of this and with much consideration Bruce is stepping away from the career that has meant so much to him. This is a really challenging time for our family and we are so appreciative of your continued love, compassion and support... As Bruce always says, “Live it up” and together we plan to do just that.”
The RED actor has five children, Rumer, 34, Scout, 31 and Tallulah, 28 from Moore, and Mabel, 10, and Evelyn, 8 with Heming Willis.
