Radar obsessively tracks the boldface names in the country’s top gossip columns—Rush & Molloy, Cindy Adams, Page Six, Liz Smith, Gatecrasher, and MSNBC’s The Scoop …

Robert De Niro: Three mentions (Rush & Molloy, Gatecrasher, Page Six). The Goodfellas star makes the Tribeca Film Festival party rounds.

Alec Baldwin: Two mentions (Rush & Molloy, Page Six). The oldest Baldwin brother tapes a segment for The View where he apologizes for cussing out his daughter, Ireland, then explains that he wants to leave 30 Rock to spend more time with that selfsame pre-teen—but NBC brass will not release him from his contract.

Katie Couric: Two mentions (Rush & Molloy, Page Six). Poor Katie. Her CBS colleagues Bob Schieffer and Lesley Stahl allegedly talk smack about Katie to Philadelphia Inquirer columnist Gail Shister. Apparently, “Lesley totally dismisses Katie.” How can you dismiss a woman who has the Pussycat Dolls hit “Don’t Cha” as her ring tone?

Nicole Miller: Two mentions (Rush & Molloy, Gatecrasher). New York’s fashionista set comes out to celebrate Nicole Miller’s 25 years in the design business at the Chinatown Brasserie.
