RENÉE Zellweger (above), who hasn’t been romantically linked to anyone since she divorced country singer Kenny Chesney, had a date Saturday night with MSNBC legal correspondent Dan Abrams, who has a thing for actresses. The two were spotted at a cozy table for two at the American Hotel in Sag Harbor. Abrams has previously dated Elisabeth Rohm of “Law & Order,” Jaime Murray of “Dexter” and Elle Macpherson, who once had a three-picture deal with Miramax.
