‘The Sopranos’ vs. ‘Entourage’?

WATER benefit for Riverkeeper. SF Gallery, 663 Fifth Ave., nr. 52nd St., 6:30 p.m. Sponsored by Salvatore Ferragamo; expected guests include Lorraine Bracco, Ivanka Trump, Lauren Bush, Amanda Hearst, Vanessa Q. Rockefeller, Ana Lucia Vanderbilt, Chupacabra Winthrop-Gugelman, and Mo’nique Astor.

VH1 party for The Agency. Bryant Park Hotel, 40 W. 40th St., nr. Sixth Ave., 9 p.m. No hugely celebtastic guests are confirmed, but “The Agency” is the Wilhelmina modeling agency, so you can probably count on Piven to be there.
