CNN is reporting rumors that Senator Clinton will be making a surprise appearance tonight on Saturday Night Live.

Days before a crucial set of primaries, Democratic presidential candidate Hillary Clinton is expected to make a surprise appearance on Saturday Night Live tonight, an entertainment industry source tells CNN.

A spokesman for Saturday Night Live would not confirm the appearance, saying only, “It’s a live show, anything can happen”

Clinton did not arrive for a campaign charter flight from Dallas to Columbus, Ohio Saturday evening. The campaign would not say where she was.

Democratic candidate Barack Obama appeared on Saturday Night Live unannounced around Halloween, and GOP candidate Mike Huckabee did a bit on the show’s Weekend Update last Saturday. Clinton is also scheduled to appear on John Stewart’s “Daily Show” Monday, on the eve of voting in Ohio, Texas, Rhode Island and Vermont.
