What’s a Grammy show without those who’d dare stun us with their choice of threads, crazy antics, or mere celebrity presence? Read on to see why these five stars incurred a little gasp from yours truly.

Was that a supernova? A planetarium constellation? A walking hurricane? Oh, Lady Gaga, you never cease to amaze me. This was just one of the exclusive Armani Privé ensembles she put on that night.

The punk-rocker is now a lady! Pink surprised everyone with her crystal-encrusted degradé gown.

Sorry, Imogen Heap. Nobody can ever outdo Lady Gaga, but you gave it a good shot.

Ladies and gentlemen, Ricky Martin is alive! I repeat, Ricky Martin is back!

Glambert rocked, as usual. Why, Adam Lambert could wear a real vampire’s costume from the 1800s and still make it look hot.

Who is Shaila Durcal, or better yet, what in the world was she wearing?!

I give David and Cathy Guetta the “rocker couple of the night” award.

Oh, Britney. Your see-through, black lace Dolce & Gabbana dress over a bodysuit and fishnet stockings just wasn’t cutting it.

Did Ciara just have a chat with Britney before heading to the Grammys?
