Legendary singer Frankie Valli will guest star in an upcoming episode of US TV drama Hawaii Five-0.
According to Entertainment Weekly, The Four Seasons' front man will play a character called Leonard Campbell in an episode set to air Stateside in November.
Campbell is the fiancé of Carol Burnett's Aunt Deb, who is an ex-shop teacher with Stage 4 leukemia. The couple are planning to marry in Oahu after meeting at a cancer support group.
However, suspicious cop Steve McGarrett (Alex O'Loughlin) doesn't trust him, and believes he is lying to his aunt about his past.
Frankie Valli is not new to acting as he previously starred in The Sopranos as Rusty Millio for seven episodes between 2004 and 2006.
Hawaii Five-0's fifth season will premiere in the US in September and will follow on RTÉ Two.
