SAG Awards nominees are waking up to a pretty morning here in L.A., though it’s unclear if the weather will hold through the day. But it doesn’t matter. Regardless of weather, the stars always manage to look unruffled when they emerge from limos onto the red carpet; today will be no exception, I’m sure. Activity on the red carpet gets underway today with William Shatner offering a champagne toast at about 3 p.m. PT. I’ll be there at 2 p.m. PT, 5 p.m. ET using Twitter to send updates to the right rail.
