I swear I just happen upon these things. Same drill as the last post kids; if you mute Lady Gaga's "Bad Romance" video and play Britney's Circus, Gaga's clip fits in pretty well with the song. However, they are different lengths so it's not as seamless as the "Single Ladies/Vivrant Thing" mashup. Madonna's "Vogue" can also kinda work in a pinch (you know I had to throw Madge into the mix lol:). Try them out below:
