Katy Perry's Cleavage Stole The Show At The Grammys

Katy Perry abided by CBS' no-nudity "Wardrobe Advisory" at the Grammy Awards by wearing a mint green Gucci gown that fully covered her body — save for a keyhole cut-out showcasing the singer's ample cleavage, which ended up stealing the show.

And Katy's cleavage had quite the star-studded night.

First, it posed on the red carpet.

Even Katy couldn't keep from looking down.

Then it posed with "Girls" star Allison Williams:

Her boyfriend, John Mayer, tried to avert his eyes.

Then, it presented an award on stage:

Lena Dunham later tried to shake hands with it:

Taylor Swift and the girl behind her were in awe of it:

Drake embraced it:

The boys of FUN posed with it:

And Ellen DeGeneres, along with wife Portia de Rossi, simply could not believe it!

... Still.
