There was a major Black Pack invasion at the 2007 ShoWest convention in Vegas this week. And you can check out all the hot actresses here. But who knew Allison Janney – best known for her sharp-witted but usually matronly attired White House Press Liason CJ Cregg on "The West Wing" had gams this great? This pair may just make the much ballyhooed musical "Hairspray"  worth watching. I said may.
