Britney Spears' former husband Kevin Federline is to guest-star in the next series of teen drama One Tree Hill.
The dancer and aspiring rapper, 29, is to play a cocky rock singer in several episodes of the show, a publicist said.
His casting follows a cameo appearance on police procedural series CSI: Crime Scene Investigation last year.
Centred around high school basketball captain Lucas Scott - played by Chad Michael Murray - One Tree Hill is shown on Channel 4 in the UK.
According to showbusiness trade paper Variety, the fifth season will "fast-forward" over the characters' college years and be set four years in the future.
An online diary will fill in the gaps in the plot before the series airs in early 2008.
Federline is due to start filming his scenes this week in Wilmington, North Carolina, where the show is set.
