Robin Williams may have been struggling during the last months of his life, but he maintained his generous spirit.

The actor, who took his life a week ago at the age of 63, recorded a special video for a terminally ill New Zealand woman just months before he died. Superfan Vivian Waller — a 21-year-old woman suffering from lung, bowel, and liver cancer — made a bucket list shortly after her diagnosis and among the five items listed was meeting Williams.

"Hi Vivian, it's Robin Williams here saying hey, girl. What's going on down there in New Zealand? I'm sending all my love to you, Jack, and Sophie," the star is heard saying in the video, name-checking Vivian's husband and 1-year-old daughter. "Mark this off your bucket list."

Williams then claims that he's "channeling Matthew McConaughey," and says, "Hey, hey, hey. What's going on? It's alright, alright, alright."

He ends with, "Much love to you, baby," and blows a kiss.

Waller's husband, Jack, told Sunday Star Times in Auckland that his wife was thrilled beyond belief to receive the personal video in March. However, he noted that he had not yet discussed Williams's suicide with his wife because it was too emotional of a topic.

Jack added that he decided to share the very personal message from Williams because, "We love him. We want to show people how awesome a person he was."

Vivian is currently receiving care at a hospice in Orewa, New Zealand. While she continues her battle against cancer, her husband said that, after a series of failed attempts, chemotherapy is no longer an option.

The Good Will Hunting and Dead Poets Society actor was known for being generous with his time and money when it came to charity endeavors and worked with Comic Relief, the Christopher & Dana Reeve Foundation, the LiveStrong Foundation, and St. Jude Children's Research Hospital, among other organizations.
