Over the past few months, we've seen actors, tyrannical world leaders (twice), athletes, American Idol wannabes, weirdos and a bald Britney Spears.

They may not be true dead-ringers, but when The Hollywood Gossip's celebrity look-alikes feature makes an appearance, entertainment is a given.

Take Volume 34, below. No one (we think) would actually mistake Mary-Kate Olsen for ET: The Extra-Terrestrial in drag, but when you take a look at them side-by-side, you will notice distinct similarities...

That's ET on the right, in case you were confused. That crazy, loving alien sure was good for comic relief when he landed on Earth a quarter-century ago.

While other celebrities, such as Nicole Richie, might seem more like life forms from other galaxies, the Olsen Twins can hold their own... especially when they wear ridiculous outfits like this one... which is frequent.

Oh, and with Mary-Kate in that picture are the Greek God of Poontang (her ex-boyfriend, Stavros Niarchos) and some old lady who has no idea she's being mocked on a celebrity gossip site right now.

Think Brody Jenner would hit that? We wouldn't put it past him.
