REESE Witherspoon, basically movieless right now, might be cooking up a TV idea? A reality “Sex and the City” ensemble-type operation about wives in New York? Might Harvey Weinstein be involved? My 20/20 hearing picked up whispers. Nobody’s talking. But should this great idea be so? Reese Witherspoon on television. What could be next? Radio?

SO are tender warm love-me-love-me-not Valentine gifts being prepped? Like vanilla fragrance Taken now being sniffed by Kirstie Alley and Melanie Griffith? No. Sensual romantic Channel 1 anchor Pat Kiernan’s taking the family skiing . . . He could consider feeding them at 82nd & First’s Il Tesoro restaurant, whose A.J. Black owner/chef has a Sicilian mom, Jewish dad and serves great Italian food.

SUNDANCE. Bill Pullman, Billy Baldwin, Adrian Grenier were at the StyleCaster party . . . Grand Ole Oprah note.

Gstaad residents saying staff vacuumed Valentino’s driveway before Anne Hathaway arrived.

MADONNA. Strict with daughter Lourdes, who is taking snowboarding lessons and is demanded to be home by 1 a.m. Mommy’s new boyfriend, so young his own mother won’t let him cross the street alone, is Brahim Zaibat.

Kristen “House of Lies” Bell insisting she’ll eat pancakes if she wants to and, “I’m saving for that rainy day so if my career ends tomorrow I’m OK.”

MARK Sanford, South Carolina’s ex Gov who lied about hiking the Appalachian Trail to cheat on his wife in Argentina? Who either couldn’t nail a local bimbette or doesn’t believe the Made in America label? In the mold of Spitzer, Weiner, Schwarzenegger and Newt Gingrich, he’s trying a comeback and wants into Congress. Great idea. Next up, Madoff will give knitting lessons in the can.
