Loose LipsOh my gawd, y'all: sources say Britney Spears will host Saturday Night Live on November 22nd! • Speaking of SNL, remember former castmate Victoria Jackson? Well she's in a new ad denigrating fellow SNL alum/ democratic Minnesota Senate candidate Al Franken. According to the Huffington Post Jackson wrote on her website, "I don't want a political label, but Obama bears traits that resemble the anti- Christ and I'm scared to death that un- educated people will ignorantly vote him into office." • Sarah Silverman will appear with her on-again, off-again bf Jimmy Kimmel as a guest on his late night talk show Thursday night. Maybe this time she'll sing about fucking Ben Affleck. Or even better, Casey![Celebuzz, HuffPo, Star]
