Two pieces of Boston Legal casting news hit my Blackberry as I took a break from hanging with the Tree Hillers down here in North Carolina. (Check my Facebook page for updates on and photos from that!)

For starters, Catherine Piper is returning to Boston this season, again played by guest-star Betty White. Catherine is one of the legal dramedy's most colorful visitors, having partaken in a murderous arc a few seasons back, and served a stint as the law firm's sandwich lady.

Also on board for a guest gig is Kimberly Williams-Paisley, best known as Father of the Bride's bride and from her According to Jim run as Cheryl's sis. Thus far, no deets on KW-P's role or story. - Matt Mitovich
