Hot 100 topper Ke$ha made the talk show rounds this week to promote her new album, "Animal," visting Ellen DeGeneres on Tuesday afternoon and Conan O'Brien last night. Both performances were of her No. 1 hit "TiK ToK," and the choreography was nearly identical. Ke$ha did switch up her look considerably for the nighttime gig, though, changing from a casual T-shirt and jeans to a studded, black lace ensemble. Ke$ha also surprised O'Brien with a present in his mug, but it's completely unclear whether he liked it.

Believe it or not, these were just Ke$ha's second and third appearances on national TV. The first came last fall, when she appeared on MTV's now-cancelled "It's On with Alexa Chung." Here's hoping O'Brien's show isn't about to meet the same fate, since it's just been reported that Jay Leno is taking back his old time slot.
