Redmond is being given a leave pass from his sober-living facility to honor his mother, in what will be an emotional reunion.

“Redmond’s coming,” Ryan told photographers Thursday while hosing down his driveway at his Malibu home.

Ryan won’t reveal where they are paying tribute to the late Charlie’s Angel Star, because he didn't want to scare Redmond.
