The last time we heard about a semi-celebrity cameo on Gossip Girl, it made perfect sense - Lydia Hearst is a bonafide UES socialite herself, and to say that she'll be "acting" on the show is almost a funny stretch. But now we're hearing about a much funnier cameo, possibly airing this Monday - Lisa Loeb. Apparently, Rufus' band, Lincoln Hawk, one of the "best forgotten bands of the 90's, will play at some kind of reunion concert at which Lisa Loeb will undoubtedly perform "Stay" while perched atop a lone stool. We're praying she has lines. Get ready for fake glasses everywhere!
