Holy crap!!!
I just read this on TFN, rather shocking... if it's true. (The last bit is off topic, but consider it a bonus.)
Spoiler:
Padme is killed by Anakin. He uses the force 'strangle' on her and goes a little too far. He doesn't mean to kill her.
Also, when Anakin wakes up as Darth Vader and is told what happened to him he becomes so angry he rips apart the room he's in with the Force.And lastly, when Mace Windu confronts Palpatine, Palpatine's electricity bolts deflect off Windu's saber and into Anakin's eyes. Anakin flips out again and lops off Mace's arm.

Spoiler:
Let's put it this way... Padme's ultimate fate is still unknown. Lucas covered BOTH scenarios during filming and left some things open for change for the pickups next year if need be. And this was actually pretty easy. It doesn't really affect the rest of the story much at all, because either she dies... or everyone thinks she's dead (besides Bail & Co of course) and she lives out the rest of her life in tragic anonymity. It will all come down to Lucas' final decision on whether or not he wants her to die within the context of EP3 itself. And my contention is unless he intends of ammending that scene in ROTJ, she'll survive EP3. Either that or, like I said, one of the dumbest little plot holes ever is born.
Well truth has it that, Lucas is said to he is going to make Padme's death a cheesy one just for fun cause he likes to tease his fans or something they say it will be almost as cheesy and Jango fett getting it. They said that once he thought of having her fall down stairs and die. check out http://www.supershadow.com check out major spoilers from an inside source.
