Wait... who's that kissing Justin Timberlake?
And who are those women dressed in drag?
And which True Blood star is donning an eye patch alongside Lady Gaga?
While the recent music videos that have garnered the most attention have involved Nicki Minaj Twerking and/or Miley Cyrus naked on a wrecking ball, it's easy to forget that a number of non-singers have made cameos in a number of popular videos over the years.
Such as, yes, Kristen Stewart in drag. Or Jake Gyllenhaal as a tennis player.
Cycle through the following music video cameos and ask yourself: What was that star doing there?!?
