News Flash! (Make It Two, Actually.) Norah O'Donnell Prepares for Twins.

You might not know it to see her on TV, but Norah O'Donnell is pregnant. Reeeallly pregnant. As in, she's due to deliver twins in two weeks.

"When you're anchoring, they really only show you from here up," the NBC and MSNBC Washington correspondent told us, drawing an imaginary line across her chest. She said she doubted viewers can tell, "unless my face has gotten wider?" No, not really. She did show off the belly on-air last week, though, for a "Today" report on the very pregnant Rep. Cathy McMorris Rodgers (R-Wash.), who went on to give birth to a son just days later.

O'Donnell, 33, and her formidable silhouette stole the show Tuesday at a champagne book party she co-hosted at the Ralph Lauren boutique in Chevy Chase for Jill Kargman, N.Y.C.-based chick-lit author turned mommy-lit author of a new novel, "Momzillas." O'Donnell said she was stunned to learn she was carrying twins, but her restaurateur husband Geoff Tracy "cried. He was, like, this is the greatest thing ever." They picked the names for the boy and girl last weekend but no, they're not telling yet, so that you won't go telling them why you don't like their picks.

Since you're wondering: The cover girl for an upcoming issue of Pregnancy magazine has gained 36 pounds. "I eat healthy," she said.

A Leading Candidate for a Gig at NPR

Cate Edwards, the presidential candidate's daughter, will begin her internship at NPR later this month.

NPR legal correspondent Nina Totenberg narrowed hundreds of summer intern applications to a dozen promising candidates and began phoning the finalists, but swears it wasn't until after she interviewed Harvard Law School's Catharine Edwards that she realized the 25-year-old -- better known as Cate -- is the daughter of presidential candidate John Edwards .

"I said to myself, 'Oh, you idiot,' " said Totenberg, who wanted to offer Edwards the job and appealed to her bosses; they gave the green light, since the election is still 18 months away. Totenberg's new intern starts later this month; no word on how much time she'll spend in Washington and how much on the campaign trail.

Mayor/marathon man Adrian Fenty ran the ACLI Capital Challenge three-miler pretty fast yesterday morning -- 18:47 -- but not fast enough to beat Rep. Bart Gordon's blistering 18:24, besting a field of 23 members of Congress. It was the 18th time the Tennessee Democrat has posted the best time among officeholders in the annual race, which benefits the D.C. Special Olympics. John Thune (R-S.D.) was the fastest of 12 senators. Rep. Jean Schmidt (R-Ohio) was the fastest female rep, while Sen. Kay Bailey Hutchison (R-Tex.) was the fastest female senator -- which is to say she beat the other one in the race along the Anacostia riverfront, Lisa Murkowski (R-Alaska).

Barack Obama and John Kerry having dinner Tuesday night at the Four Seasons Hotel. The two senators, both in navy blue suits, spent three congenial hours together. Obama ate hamachi salad and scallops; Kerry had the octopus salad and striped bass.

Mike Bloomberg and Chuck Hagel dining together last night at the Palm. The New York mayor had a New York strip steak, the Nebraska senator had wild halibut, and each polished off a glass of merlot and mixed berries for dessert. They were deep in conversation for two hours; since both are mulling presidential bids, who was courting whom?
