Alyssa Milano has signed on to star in a comedy pilot for ABC only a few months after her last project for the network got scuttled. The “Charmed” star will play a single mom in a pilot from writer Ricky Blitt. The network has also cast “Lipstick Jungle” star Kim Raver in Shonda Rhimes’ drama “Inside the Box” – which could be further bad news for the not-quite-cancelled NBC series, as now two of its leads have taken pilot roles.

Milano, previously shot a pilot comedy show called “Single with Parents” that ABC picked up for midseason but then decided not to air, citing creative issues. In the new pilot (Inside the Box), she’ll play the new girlfriend of a guy (Eric Christian Olsen) who’s torn between her and his needy best friend.

Raver, whose credits also include “24″ and “The Nine,” will play a reporter in “Inside the Box,” which is set at a network news operation in Washington. Like Price’s role in another ABC project, “Eastwick,” Raver’s part here would defer to “Lipstick Jungle” should the show return. When two of a show’s three leads seek other work, though, that’s not a good sign.
