Grey's Anatomy : who's wearing the wedding dress ?

ABC/RON TOM, ABC/RANDY HOLMES

From Kristin : "Do not read this post unless you are positive you want to know who's wearing the wedding dress in the Grey's Anatomy season finale.

Seriously.

We're not kidding.

It's like losing your virginity—once the innocence is gone, you can't ever get it back, and you might just feel dirty afterward.

Make good decisions here, people...

OK, ready to be spoiled rotten?

In that case, read on and then send your thank-you vibes to the spies like us who sent in the following report.

One of my coworkers was in Los Angeles on business, and when I called her and told her about Grey's filming the wedding scene, she freaked and found the set.

She was there for the lunch break (she said there were two or three paps there too) but she said later Katherine Heigl was standing in the doorway with T.R. Knight, and she was smoking in a wedding dress. She had a big jacket/robe thing over it, but she said there was no doubt it was a wedding dress. She said Katherine was only in the doorway a minute or two before they called her back in, but she has no doubt that it was a wedding dress.

Should you trust what a friend of a friend of a friend has to say about the sitch? Well, you can decide for yourselves, but every part of this rings true to us.

What say you? Is an Alex-Izzie wedding a good idea? What do you think this means for Mer and Derek? Have they already gotten hitched in the 100th episode (the one before the finale) or did something bad happen, so Izzie took over Mer's wedding plans, Stella-on-HIMYM style?

Post your theories and reactions in the comments, and for that matter, give it up for Shonda and company, who have made this second-half of season five some damn compelling television. Seriously, who among us is not dying to know: What happens next?!"

I KNEW there would be no MerDer wedding this season !! He just poposed ! Whereas Izzie is dying so it's sort of makes sense that she would want to do this !! Stupid ! But it makes sense. She could also just be trying on the dess for some reason, whether the MerDer wedding happens or not. We'll see.
