When CBS News anchor Katie Couric isn't asking Sarah Palin gotcha questions, she's doin' Da Butt, or the Lambada, or whatever white ladies do when the Black Eyed Peas are on the sound system. More unbelievable images after the jump.

UPDATE: We've learned that these are from the after-party celebrating Couric's debut as anchor of the CBS Evening News. Oh, lord.

A tipster sent us these photos after finding them in a Facebook photo album called "Four Martini Mimimum" and says they were shot in 2006. We've asked CBS News for information about where, when, and why they were taken—we think it's a toss-up between wedding and bar mitzvah. Or maybe a birthday party? Whatever the event: Katie Couric, you now have a standing invitation to any Gawker Media party.
