A Yeas & Nays spy tells us that B-52s frontman Fred Schneider partook in a little late-night karaoke at the Dupont Italian Kitchen on Tuesday. Schneider sang the band's popular hits "Love Shack" and "Rock Lobster." The B-52s performed at the 9:30 Club on Wednesday night. Meanwhile, Oscar-winner Jamie Foxx was spotted canoodling with his so-called "mentee," actress and model Brittany Loren, at the Hennessy Black BET Honors afterparty at the Park at Fourteenth on Saturday night. A Yeas & Nays spy tells us Foxx was a total gentleman and held her hand the entire evening. Actress and Washington Ballet Company alumnus Nicole Ari Parker and her husband, Boris Kodjoe, were also seen tearing up the dance floor at the swanky affair. We're told the good-looking pair were dancing the Dougie. Aww yeah.
