Singer/guitarist Chaplin will join the rock icon for select dates on his upcoming tour, which will also feature guest spots from Beach Boys founding members Al Jardine and David Marks.
Chaplin, who was a Beach Boy in the early 1970s, will be part of Wilson's performances in Florida, New York City, Las Vegas, Oakland and Los Angeles.
Wilson tells the Los Angeles Times, "Blondie was one of my favourite singers in the '70s. He blew my mind with Sail on Sailor, and he also sang on a song called Funky Pretty, on the Beach Boys' Holland album.
"Until two weeks ago, I hadn't seen him since 1974. It was great to see him again. He came into the studio and sang on one of my new tracks called He Come Down - he sang it great! It will be fun to have him at a few of our concerts."
Wilson is touring North America from 27 September (13) on a split bill with Jeff Beck, who also has been contributing to the Beach Boys star's new solo album.
The Good Vibrations singer and Jardine and Marks last hit the stage together last year (12) for the 50th anniversary Beach Boys reunion tour, which ended when former bandmates Mike Love and Bruce Johnston announced plans to resume touring with an alternative group.
