COFFIN FOR TWO?

Anna Paquin and Stephen Moyer aren't wasting any time: the "True Blood" twosome are already hunting for their own love nest after getting engaged earlier this month. The co-stars - who play onscreen lovers psychic Sookie Stackhouse and vampire Bill Compton - hit an open house and checked out two moderately-priced homes with a Realtor in Santa Monica over the weekend. The pair is said to be looking for a cozy and modern abode with additional bedrooms for Moyer's two children, Billy, 8, and Lilac, 5.
