New faces: Jaime Pressly, the beautiful, blonde star of movies like Joe Dirt and Tomcats, makes a splash as a mermaid, with Phoebe (Alyssa Milano) joining her in the sea. And Ken Marino - who, as Professor David Wilder, got Joey steamed up in Dawson's Creek - had a similiar effect on one of the Halliwell sisters.
What to expect: We discovered at the end of last season that Piper (Holly Marie Combs) is pregnant, and this season, she will become the first of the sisters to have a baby. But as the baby is the child of a witch and a whitelighter (Brian Krause), who knows how it will turn out?
Phoebe tried to divorce Cole (Julian McMahon), but he wants her back. He's going to cause more problems for the sisters before he finally disappears.
Meanwhile, Paige (Rose McGowan) gets her first charfe as a whitelighter - and is shocked to discover his identity.
