Alec Baldwin and Hilary Rosen ( AP; Marissa Rauch)

They did!!! We learn this via a passing reference in Vanity Fair’s new cover story: How he and the veteran Democratic operative/pundit lived across the hall from each other at George Washington University’s Thurston Hall, and, oh yeah, dated. “He was passionate about politics,” Rosen, the former chief of the Recording Industry Association of America, told the magazine. “He was funny — and I won’t say he was lighthearted, because he was always ambitious; he always wanted to have an impact and be in the thick of things.”

Wow, who knew? “He is better off with [new bride] Hilaria,” she told us in an e-mail. “Very happy for him!”
