When Carol Burnett returns to Hawaii Five-0, she’ll be bringing a Jersey Boy with her: EW has learned exclusively that Frankie Valli will guest-star on an upcoming episode of the CBS drama.
The legendary Four Seasons frontman will play Leonard Campbell, the fiancé of Burnett’s Aunt Deb, who is an ex-shop teacher with Stage 4 leukemia. The couple met at a cancer support group and have now come to Oahu to get married. However, McGarrett is suspicious that Leonard is not being completely honest with his aunt about his past.
Valli, whose previous TV credits include The Sopranos, will appear in an episode slated for November.
Hawaii Five-0 returns Sept. 26 at 9 p.m. ET on CBS.
