Seriously? OMG! WTF?

Yvonne’s Strahovki shot a music video for College Humor combining Three Pop Stars into One Song and I will never watch her on Chuck the same way. As we know Sarah Walker has gone in disguise on Chuck, but we have never seen her as Katy Perry, Ke$ha and Lady Gaga before this video and I kind of hope we never do again. Although she actually looked good as Justin Bieber at the end.
BTW when it comes to the song, I never realized how much the three pop stars all sounded alike until now.
