Nick Lachey will join the cast of The WB's veteran witch series Charmed for six episodes next season, according to The Hollywood Reporter. The singer-actor and star of MTV's reality series Newlyweds: Nick & Jessica will play a guy hired as a ghost writer for witch Phoebe Halliwell's (Alyssa Milano) advice column who ends up romantically involved with her, the trade paper reported.

Charmed begins its seventh season this fall.

Sounds like series 6 will be interesting as she was 'romantically involved' with the guy who owns the paper at the end of the fifth series.

Anyone know when the sixth series starts on Five?

The new seasons usually start in September.

The UK tends to start new series in January
