Frankie Valli Heads to Hawaii Five-0 as Carol Burnett's Mysterious Fiancé

Four Seasons singer Frankie Valli will "Walk Like a Man" right down the aisle on Hawaii Five-0 this season.

As we previously teased in Mega Buzz, Carol Burnett will be returning to the show in Season 5 as Deb, the aunt of McGarrett (Alex O'Loughlin), and will be bringing a fiance with her, whom she met in chemotherapy. Valli, 80, has been tapped to play her beau, Leonard Campbell, TVGuide.com has confirmed.

"They're going to have this whirlwind romance, and they're coming to Hawaii to get married because they realize both of them don't have much time left," showrunner Peter Lenkov told TVGuide.com last month.

Aunt Deb may be a little too eager to head down the aisle though, as McGarrett will have some suspicions about Leonard's past, according to Entertainment Weekly, which first reported the news.

The wedding episode will be the eighth of the season and is scheduled to air on Nov. 21, Lenkov tells TVGuide.com.

Hawaii Five-0 kicks off Season 5 on Friday, Sept. 26 at 9/8c on CBS. Are you looking forward to meeting Valli's character?
