JoJo JoJo

Pop singer JoJo has been cast in a special episode of CBS's Hawaii Five-0 that will air after the AFC Championship game on Sunday, Jan. 23. The 20-year-old will play Courtney Russell, the daughter of a Tsunami Warning Center scientist who goes missing on the eve of a big storm hitting the Honolulu coast.

The episode will also feature Bones favorite Joel David Moore as Sheldon Tunney, the missing scientist's second in command. I'm hearing as well that the series is getting closer to casting its fifth series regular team member, likely a woman, to begin shooting at month's end for an on-air debut in March.
