Drew Barrymore and Justin Long SPLIT? What the ... ?

Drew Barrymore's rep tells Us Weekly that she and Justin Long have split up.

Huh?

Just like that? No arguments, no seeing other people?

But it was just a little while ago that Justin said his cheeks hurt, he was so happy.

What went wrong? Is Drew really a commitment-phobic ditz? Is she just in love with love? Don't say we didn't warn you, Justin. Click here to refresh your memory.

For crying out loud, their movie "He's Just Not That Into You," isn't even out yet! (It's been delayed until February, just in time for Valentine's Day.) Man, you'd think they would have the decency to stay together until then. But nooooo.

What do you think happened?
