Guess The Extraterrestrial Pop Star!

Katy Perry used "E.T." as the perfect opportunity to dress up in flowy-costumes and to float through space, before falling in love with a nice robot boy before they walk off into the sunset. There're kaleidoscope-effects, Kanye West, and cuts to National Geographic-style clips of animals going at it, which reminds us that Katy's world is not ours. (After all, Arthur?) It's all so out there.

But it feels like we've seen this before. For just about as long as they've been making videos, musicians have been taking the superstar thing far too literally. Can you guess which scenes the following videos are from?

This is Katy's extraterrestrial happily-ever-after.

1. Hint: Having this midriff-baring alien baby mama on PlentyofFish.com serves no other purpose besides nanny-money product placement, so why doesn't this singer just go all the way and get sponsored by FedEx?

2. Hint: Kim Kardashian.

3. Hint: Putting this guy on the back of an elephant is animal cruelty.

4. Hint: Special effects have gotten better since 1969, but not necessarily the songwriting.

5. Hint: "Alternative music."

Answers after the jump.
