UPDATE ON ROB LOWE: Be sure to check out Brothers & Sisters exec producer Jon Robin Baitz' brand-new TVGuide.com blog entry regarding Lowe joining the cast.

As first spilled by the Ausiello Report, former West Winger Rob Lowe is joining ABC's Brothers & Sisters as a Republican senator and romantic interest for Calista Flockhart's Kitty (and no, that was not a euphemism). Lowe will appear in at least six episodes; Mike has the details.... Per Reuters, Alicia Witt ( Cybill) will star in Blue Smoke, a Lifetime movie based on the Nora Roberts best-seller about a female arson investigator haunted by a pyromaniac stalker. Scott Bakula, Talia "Adrian!!!" Shire (as Witt's mother) and Matthew Settle ( Brothers & Sisters) also star.... Relative newbies Rachel Specter ( Entourage), Brendan Miller ( Accepted), Anna Osceola, John Keefe ( The Practice), Christopher Todd ( The Sopranos) and Jocelin Donahue will populate the Comedy Central pilot Not Another High School Show, which promises to skewer the likes of The O.C. and Dawson's Creek. Awesome.
